1. Uniqueness of the Higgs line {A,E,U}

1.1 Identification of the Higgs field [T]

In UHM the Higgs field is identified with the $E$-$U$ coherence in the $\bar{3}$-to-$\bar{3}$ sector:

$H \sim \gamma_{EU} = |\gamma_{EU}| e^{i\theta_{EU}}$

Dimensions $E$ (evaluation) and $U$ (unity) belong to the $\bar{3}$-sector $\{L, E, U\} = \{4, 5, 6\}$. The pair $(E, U)$ defines the electroweak channel: $\text{Gap}(E,U) = 0$ corresponds to a weak doublet, $\text{Gap}(E,U) \neq 0$ — to a singlet.

Theorem 1.0 (Identification $H \sim \gamma_{EU}$) [T]

[T] Theorem

The identification $H \sim \gamma_{EU}$ is strictly proved from four independent [T]-results: categorical uniqueness of the pair $(E,U)$, uniqueness of the Higgs line, $SU(2)_L \times U(1)_Y$ quantum numbers, and nonzero vacuum expectation value from the unique vacuum.

Theorem. The coherence $\gamma_{EU}$ is the unique candidate for the Higgs field in UHM, and the identification $H \sim \gamma_{EU}$ is proved from the following chain.

Step 1. Categorical uniqueness of the pair $(E,U)$ [T] (T-42a).

The formula $\kappa_0 = \omega_0 \cdot |\gamma_{OE}| \cdot |\gamma_{OU}| / \gamma_{OO}$ categorically singles out exactly the pair $(E,U)$ via morphisms $\mathrm{Hom}(O,E)$ and $\mathrm{Hom}(O,U)$. No other pair of dimensions has this property: replacing with $\{L,U\}$ removes $\mathrm{Hom}(O,L)$ from $\kappa_0$; replacing with $\{L,E\}$ excludes $U$, breaking the normalization $\mathrm{Tr}(\Gamma) = 1$. Uniqueness is proved — see Theorem of FE-uniqueness [T].

Step 2. Uniqueness of the Higgs line $\{A,E,U\}$ [T] (Theorem 1.1).

Through any two points of $\mathrm{PG}(2,2)$ there passes exactly one line. The unique Fano line containing both points $E = 5$ and $U = 6$: $\{5,6,1\} = \{A,E,U\}$. This line defines the electroweak sector — see Theorem 1.1 [T].

Step 3. Quantum numbers of $\gamma_{EU}$ coincide with those of the SM Higgs doublet [T].

From the electroweak uniqueness theorem (§2.3a [T]): the pair $(E,U)$ forms the doublet $2_{EU}$ under $SU(2)_L$. The coherence $\gamma_{EU}$ — a bilinear form connecting $E$ and $U$ — transforms as $(2, +1/2)$ under $SU(2)_L \times U(1)_Y$. This is exactly the quantum numbers of the SM Higgs doublet.

Step 4. Nonzero VEV $\langle\gamma_{EU}\rangle \neq 0$ breaks $SU(2)_L \times U(1)_Y \to U(1)_\text{em}$ [T].

From Theorem on the unique vacuum T-64 [T]: the unique global minimum of $V_\text{Gap}$ has $|\gamma_{EU}|_\text{vac} = \varepsilon_{\bar{3}\bar{3}} \approx 10^{-17}$ (in units of $\omega_0$), giving $\langle\gamma_{EU}\rangle \neq 0$. A nonzero vacuum expectation value of a field with quantum numbers $(2, +1/2)$ uniquely realizes spontaneous breaking $SU(2)_L \times U(1)_Y \to U(1)_\text{em}$.

Conclusion. All four steps rely exclusively on [T]-results. The identification $H \sim \gamma_{EU}$ follows from them uniquely. $\blacksquare$

1.2 Fano–Higgs line

Definition 1.1 (Fano–Higgs line)

Definition. The Fano–Higgs line is the Fano line of $\mathrm{PG}(2,2)$ containing both Higgs dimensions $E = 5$ and $U = 6$.

Theorem 1.1 (Uniqueness of the Fano–Higgs line)

[T] Theorem

Strictly proved. Follows from the incidence axiom of the projective plane $\mathrm{PG}(2,2)$: through any two points there passes exactly one line.

Theorem. There exists exactly one Fano–Higgs line: $\{1, 5, 6\} = \{A, E, U\}$.

Proof. In $\mathrm{PG}(2,2)$ through any two points there passes exactly one line. We seek the line containing points $E=5$ and $U=6$. From the complete list of 7 Fano lines:

Line	Contains $E=5$?	Contains $U=6$?	Both?
$\{1,2,4\}$	No	No	No
$\{2,3,5\}$	Yes	No	No
$\{3,4,6\}$	No	Yes	No
$\{4,5,7\}$	Yes	No	No
$\{5,6,1\}$	Yes	Yes	Yes
$\{6,7,2\}$	No	Yes	No
$\{7,1,3\}$	No	No	No

The unique line containing both 5 and 6: $\{5,6,1\} = \{A, E, U\}$. $\blacksquare$

1.3 Combinatorics of PG(2,2): why {A,E,U} is the only possibility

[T] Theorem

Uniqueness follows from the incidence axiom of the projective plane of order 2: through any two points there passes exactly one line.

The projective plane $\mathrm{PG}(2,2)$ (Fano plane) contains 7 points and 7 lines. Each line contains 3 points; through each point pass 3 lines. Key property: through any pair of points there passes exactly one line.

The Higgs field is defined by two dimensions: $E = 5$ (evaluation) and $U = 6$ (unity). Question: which Fano lines contain both of these dimensions?

The count is exhaustive. Of the 7 lines of $\mathrm{PG}(2,2)$:

• $\{1,2,4\}$: $E \notin$, $U \notin$ — does not qualify
• $\{2,3,5\}$: $E \in$, $U \notin$ — does not qualify
• $\{3,4,6\}$: $E \notin$, $U \in$ — does not qualify
• $\{4,5,7\}$: $E \in$, $U \notin$ — does not qualify
• $\{5,6,1\} = \{A,E,U\}$: $E \in$, $U \in$ — unique
• $\{6,7,2\}$: $E \notin$, $U \in$ — does not qualify
• $\{7,1,3\}$: $E \notin$, $U \notin$ — does not qualify

Thus, the incidence structure of $\mathrm{PG}(2,2)$ uniquely determines the third element of the Higgs line: $A = 1$.

Note that this property does not depend on the choice of numbering: for any identification of $E$ and $U$ with two points of the Fano plane, the third element is determined uniquely. The duality of $\mathrm{PG}(2,2)$ (point $\leftrightarrow$ line) means that point $A$ lies on exactly 3 lines, one of which is the Higgs line $\{A,E,U\}$, and the other two ($\{A,S,L\} = \{1,2,4\}$ and $\{A,D,O\} = \{1,3,7\}$) play different roles: generational and gravitational, respectively.

1.4 Physical interpretation [I]

The third element of the Higgs line is $A = 1$ (awareness). This means:

• Dimension A is directly connected to the Higgs mechanism of mass generation.
• Generation $k=1$ (A) → third generation ($t$, $b$, $\tau$) acquires a tree-level Yukawa coupling.
• Generations $k=2$ (S) and $k=4$ (L) do not lie on the Higgs line → $y^{(\text{tree})} = 0$.

This is the foundation of the Fano selection rule for Yukawa couplings.

Generation assignment and number of generations [T]

The assignment $k=1 \to$ 3rd generation is strictly proved from the unique nonzero tree-level Yukawa coupling — see Theorem 4.1 (Assignment of 3rd generation). The complete ordering ($k=4 \to$ 2nd, $k=2 \to$ 1st) is strictly proved — Theorem 4.3 [T]. The number of generations $N_{\text{gen}} = 3$ is strictly proved from a two-sided argument ($\leq 3$ from swallowtail + $\geq 3$ from $(1,2,4) \subset \mathbb{Z}_7^*$) — see Theorem $N_{\text{gen}} = 3$ [T].

1.5 Why the E-U channel defines electroweak physics

[T] Theorem

The $E$-$U$ channel is the unique channel in the $\bar{3}$-sector not containing $L$ (interiority), making it the only candidate for chiral distinction.

In the $\bar{3}$-sector $\{L, E, U\} = \{4, 5, 6\}$ there are three coherences: $\gamma_{LE}$, $\gamma_{LU}$, $\gamma_{EU}$. Of these:

Channel	Connection	Role in SM
$L$-$E$	Interiority–evaluation	Lepton number
$L$-$U$	Interiority–unity	Baryon number
$E$-$U$	Evaluation–unity	Weak isospin (Higgs)

The $E$-$U$ channel is distinguished for three reasons:

1. Algebraic: $E$-$U$ is the unique channel in the $\bar{3}$-sector not containing the $L$-dimension. In fermionic configurations ($R \to 0$) the $L$-channels are fixed, and only $E$-$U$ remains free for defining chirality.

2. From Fano structure: in the $\bar{3}$-sector there exists one Fano line $\{L,E,U\}$. The chirality operator $\Gamma_{LEU}$ is defined by this line. $\text{Gap}(E,U)$ is the specific coherence broken by the Higgs, while $\text{Gap}(L,E)$ and $\text{Gap}(L,U)$ define the interiority level.

3. Physical: $E$-dimension $\leftrightarrow$ evaluative structure $\leftrightarrow$ electric charge. $U$-dimension $\leftrightarrow$ unification $\leftrightarrow$ weak isospin. At $\text{Gap}(E,U) = 0$ they are indistinguishable → $SU(2)_L$ doublet. At $\text{Gap}(E,U) \neq 0$ they are distinguishable → singlets.

---

2. Higgs mechanism from Gap-condensation

Theorem 2.1 (Higgs mechanism from Gap-condensation)

[T] Theorem

The mechanism of electroweak breaking via $\text{Gap}(E,U) \to 0$ is a consequence of the uniqueness of the minimum of $V_{\text{Gap}}$ in the $\bar{3}$-sector: $\varepsilon_{\bar{3}\bar{3}} \approx 10^{-17}$ is determined uniquely from positive definiteness of the Hessian (theorem on the unique vacuum [T]).

Theorem. Spontaneous electroweak symmetry breaking arises from Gap-condensation in the $\bar{3}$-to-$\bar{3}$ sector:

(a) The Higgs field is identified with the $E$-$U$ coherence:

$H \sim \gamma_{EU} = |\gamma_{EU}| e^{i\theta_{EU}}$

(b) VEV (vacuum expectation value):

$\langle H \rangle = \langle |\gamma_{EU}| \rangle e^{i\langle\theta_{EU}\rangle} \neq 0$

Nonzero VEV breaks $SU(2)_L \times U(1)_Y \to U(1)_\text{EM}$:

• $SU(2)_L$: 3 generators → 2 broken ($W^+$, $W^-$) + 1 linear combination broken ($Z$)
• $U(1)_Y$: 1 generator
• $U(1)_\text{EM}$ = diagonal subgroup (photon) — unbroken

(c) Mass of the $W$-boson:

$M_W = \frac{g}{2} v, \quad v = \langle |\gamma_{EU}| \rangle \cdot \mu_\text{phys}$

where $g$ is the electroweak coupling constant, $\mu_\text{phys} = \mu \cdot \omega_0$.

2.1 Potential in the E-U channel

The potential $V_\text{Gap}$ projects onto the $E$-$U$ channel:

$V_{EU}(\gamma_{EU}) = \mu^2 |\gamma_{EU}|^2 + \lambda_4 |\gamma_{EU}|^4 + \lambda_3 \bar{A} |\gamma_{EU}|^3 \cos(\text{phase})$

At $\mu^2 < 0$ (low-temperature regime): minimum at $|\gamma_{EU}| = v \neq 0$. This is the standard Higgs mechanism applied to the Gap potential. Higgs mass = second derivative of $V_{EU}$ at the minimum.

note

Status of parameter $\lambda_3$ [T]

The parameter $\lambda_3 = 2\mu^2/(3|\bar{\gamma}|) \approx 74$ is a geometric coefficient of the spectral action (T-74 [T]), not a perturbative coupling constant. Physical observables are defined non-perturbatively via the self-consistent vacuum $\theta^*$ (T-79 [T]). UV-finiteness (T-66 [T]) ensures structural correctness. Loop estimates are approximations to $\theta^*$, giving the right order of magnitude (error $\lesssim \times 5$). For details — see Yukawa Hierarchy.

⚠ C7: $\lambda_3 \approx 74 \gg 4\pi$ — non-perturbative regime. All loop computations with $\lambda_3$ are formally unreliable and downgraded to [H]. See warning.

2.2 Origin of $M_H \approx 125$ GeV from Gap-condensation [C]

[C] Conditional

The parameter $\lambda_4$ is determined from the Chamseddine–Connes spectral action with RG correction (see theorem on Higgs quartic [C]). Conditionality: free parameter $f_0$ in the spectral action. The octonionic correction from $V_3$ additionally modifies $M_H$.

Progress: from fitting to computation

In early versions the parameter $\lambda_4 \approx 0.13$ was adjusted from the condition $M_H \approx 125$ GeV. The spectral action (theorem on Higgs quartic [C]) determines $\lambda_4$ through the spectrum of the finite Dirac operator $D_{\text{int}}$. The remaining free degree is the parameter $f_0$, fixed by calibration to $M_H^{\text{exp}}$.

In the Standard Model the Higgs mass $M_H \approx 125$ GeV is a free parameter, fixed experimentally. In UHM the parameter $\lambda_4$ is determined by the spectral action through the spectrum $D_{\text{int}}$ (theorem on Higgs quartic [C]), and the Higgs mass arises from the structure of the Gap potential:

(a) The Higgs mass is determined by the curvature of $V_{EU}$ at the minimum:

$M_H^2 = \frac{\partial^2 V_{EU}}{\partial |\gamma_{EU}|^2}\bigg|_{v} = 2\lambda_4 v^2 + \frac{3\lambda_3^2 \bar{A}^2}{4\mu^2}$

(b) The first term, $2\lambda_4 v^2$, is the standard contribution from the quartic potential $V_4$. At $v = 246$ GeV and $\lambda_4 \approx 0.13$ we get $\sqrt{2\lambda_4} \cdot v \approx 125$ GeV — coincidence with SM.

(c) The second term, $\delta M_H^2 = 3\lambda_3^2 \bar{A}^2 / (4\mu^2)$, is the octonionic correction from the cubic potential $V_3$. It is absent in the SM and is a direct consequence of the $\mathbb{O}$-structure.

(d) Numerical estimate of the correction (at typical values of Gap parameters):

$\delta M_H^2 \approx \frac{3 \cdot (73.8)^2 \cdot (0.047)^2}{4 \cdot 16.6} \approx 5.5 \; (\text{in Gap units})$

This correction is small compared to the main term, but is nonzero and gives rise to a falsifiable deviation from SM (see section 6).

(e) Mechanism for fixing $\lambda_4$: the Chamseddine–Connes spectral action determines $\lambda_4$ via the coefficient $a_4$ and the spectrum $D_{\text{int}}$ (theorem on Higgs quartic [C]). RG evolution from the cutoff scale $\Lambda$ to $v_{\text{EW}}$ brings $\lambda_4(\Lambda) \approx 0.20$ to the observed $\lambda_4(v) \approx 0.13$ (Shaposhnikov–Wetterich result 2010). The remaining free parameter $f_0$ in the spectral action is fixed by calibration. Once it is determined from other observables, $M_H$ will become a full prediction of the theory.

3. Gap(E,U) → 0: electroweak symmetry breaking

3.1 Connection of Gap(E,U) to particle quantum numbers

$\text{Gap}(E,U)$ defines the weak isospin of elementary fermions:

• $\text{Gap}(E,U) = 0$ → doublet of $SU(2)_L$
• $\text{Gap}(E,U) \neq 0$ → singlet of $SU(2)_L$

3.2 Fermionic representations from Γ-configurations

Theorem 3.1 (Quarks and leptons as Gap-configurations) [C]

[C] Conditional

The identification of fermions with Gap-configurations is conditional on the correctness of the identification of SM quantum numbers with Gap structure (gauge correspondence hypothesis).

Theorem. Elementary fermions are identified with degenerate ($R \to 0$) configurations $\Gamma$, classified by $SU(3)_C \times SU(2)_L \times U(1)_Y$ quantum numbers:

(a) Left quark doublet $Q_L = (u_L, d_L)$:

$\Gamma_{Q_L}: \quad \text{Gap}(A,L) = \text{Gap}(S,E) = 0 \; (\text{color bonds}), \quad \text{Gap}(E,U) = 0 \; (\text{weak isospin})$

Quantum numbers: $(3, 2)_{1/6}$

(b) Right $u$-quark $u_R$:

$\Gamma_{u_R}: \quad \text{Gap}(A,L) = \text{Gap}(S,E) = 0, \quad \text{Gap}(E,U) \neq 0$

Quantum numbers: $(3, 1)_{2/3}$

(c) Left lepton doublet $L_L = (\nu_L, e_L)$:

$\Gamma_{L_L}: \quad \text{Gap}(\{A,S,D\}, \{L,E,U\}) = \text{Gap}_\text{max} \; (\text{colorless}), \quad \text{Gap}(E,U) = 0$

Quantum numbers: $(1, 2)_{-1/2}$

(d) Right electron $e_R$:

$\Gamma_{e_R}: \quad \text{Gap}(\{A,S,D\}, \{L,E,U\}) = \text{Gap}_\text{max}, \quad \text{Gap}(E,U) \neq 0$

Quantum numbers: $(1, 1)_{-1}$

3.3 Mechanism: why Gap(E,U) → 0 in the vacuum

Justification. Of the three candidates for zero Gap in the $\bar{3}$-sector ($L$-$E$, $L$-$U$, $E$-$U$), the pair $(E,U)$ is distinguished because:

1. The unique Fano–Higgs line $\{A,E,U\}$ passes through both points.
2. On this line lies $A$ = the generation with a tree-level Yukawa → maximal coupling to the mass mechanism.
3. The vacuum configuration minimizes $V_\text{Gap}$, and the minimum is reached at $\text{Gap}(E,U) \to 0$ in the $\bar{3}$-sector. $\varepsilon_{\bar{3}\bar{3}} \approx 10^{-17}$ from the unique vacuum → Gap(E,U) ≈ 0 — minimum of $V_{\text{Gap}}$ in the $\bar{3}$-sector [T] (see theorem on unique vacuum).

Hypercharge is determined by the total Gap in the $O$-sector:

$Y = \frac{1}{3}\left(\sum_{i \in 3} \text{Gap}(O,i) - \sum_{j \in \bar{3}} \text{Gap}(O,j)\right)$

3.4 Anomaly cancellation

Theorem 3.2 (Anomaly cancellation)

[T] Theorem

Anomaly cancellation for one generation is the standard SM result, automatically satisfied for Gap-configurations.

Theorem. The set of fermionic representations satisfies the gauge anomaly cancellation condition:

$\sum_\text{fermions} Y^3 = 0, \quad \sum_\text{fermions} Y = 0$

Proof. For one generation:

$Q_L(1/6)^3 \times 6 + u_R(2/3)^3 \times 3 + d_R(-1/3)^3 \times 3 + L_L(-1/2)^3 \times 2 + e_R(-1)^3 \times 1 = 0$

Fermionic representations from Gap-configurations form the same structure as one SM generation — anomalies cancel by construction. $\blacksquare$

---

4. Higgs mass with octonionic correction

Theorem T-70 (Canonical definition of $f_0$) [T]

[T] Theorem

In UHM the moment $f_0$ of the spectral action is uniquely determined through the vacuum effective action of the Gap theory on $(S^1)^{21}$:

$f_0 \Lambda^4 = \frac{1}{7}\left[V_{\mathrm{Gap}}^{\min} + \frac{1}{2}\zeta'_{H_{\mathrm{Gap}}}(0)\right]$

where $V_{\mathrm{Gap}}^{\min}$ is the potential value at the vacuum minimum (T-64 [T]), and $\zeta'_{H_{\mathrm{Gap}}}(0)$ is the log-determinant of the Hessian at the vacuum.

Proof.

Step 1 (UV-finiteness → finite functional integral). The Gap theory on $(S^1)^{21}$ with $G_2$-symmetry and $\mathcal{N} = 1$ SUSY is UV-finite (T-66 [T]). Therefore the functional integral $Z = \int [D\theta] \exp(-S_{\mathrm{Gap}}[\theta])$ is finite and well-defined without regularization ambiguity. The quantum effective action $\Gamma_{\mathrm{eff}} = -\ln Z$ is a finite, concrete quantity.

Step 2 (Unique vacuum → loop expansion). From T-61, T-64 [T]: the potential $V_{\mathrm{Gap}}$ has a unique global minimum with positive definite Hessian $H_{\mathrm{Gap}}$. Expansion:

$\Gamma_{\mathrm{eff}} = V_{\mathrm{Gap}}^{\min} + \frac{1}{2}\ln\det(H_{\mathrm{Gap}}) + O(\text{two-loop})$

Step 3 (Determinant regularization). Zeta-regularized determinant: $\ln\det(H_{\mathrm{Gap}}) = -\zeta'_{H_{\mathrm{Gap}}}(0)$. From T-64 [T]: all eigenvalues $\lambda_i > 0$ (5 positive on the orbit space), so $\zeta'_{H_{\mathrm{Gap}}}(0) = -\sum_{i=1}^{5}\ln\lambda_i$.

Step 4 (Identification with $f_0$). Coefficient $a_0$ of the spectral action: $f_0 \Lambda^4 \cdot 7$ = vacuum energy density of the internal space = $\Gamma_{\mathrm{eff}}$. Therefore:

$f_0 = \frac{\Gamma_{\mathrm{eff}}}{7\Lambda^4} = \frac{1}{7\Lambda^4}\left[V_{\mathrm{Gap}}^{\min} + \frac{1}{2}\zeta'_{H_{\mathrm{Gap}}}(0)\right]$

Step 5 (Uniqueness). All quantities on the right-hand side are uniquely determined: $V_{\mathrm{Gap}}^{\min}$ from T-64 [T], $\zeta'_{H_{\mathrm{Gap}}}(0)$ from a finite sum over 5 eigenvalues, $\Lambda = \omega_0$. $f_0$ is not a free parameter, but a definite function of the vacuum quantities. $\blacksquare$

Numerical estimate [C]

From T-64 [T], Hessian eigenvalues: $\lambda_1 = 18\mu^2$ (confinement), $\lambda_{2,3} = 6\mu^2(1 + O(\varepsilon^2))$ (spatial), $\lambda_{4,5} = 12\mu^2(1 + O(\varepsilon))$ (O-modes). With $\mu^2 \approx \omega_0^2/7$: $f_0 \approx 2.2/\omega_0^4$. Numerical value [C] — depends on exact $\varepsilon_i$.

Theorem (Higgs quartic from spectral action) [C]

[C] Conditional

$\lambda_4$ is determined through the spectrum of the finite Dirac operator $D_{\text{int}}$. The parameter $f_0$ is canonically determined [T] (theorem above); the numerical value of $\lambda_4$ depends on exact sectoral $\varepsilon_i$ [C].

Theorem. The Higgs quartic self-coupling is determined through the coefficient $a_4$ of the spectral action:

$\lambda_4 = \frac{\pi^2}{2f_0\Lambda^4} \cdot \frac{\mathrm{Tr}(D_{\text{int}}^4)}{[\mathrm{Tr}(D_{\text{int}}^2)]^2}$

This is the standard result of Chamseddine–Connes–Marcolli (2007, Thm 11.2) for the NCG Standard Model. Applicability to the UHM triple is verified:

Proof.

Step 1 (Applicability check). The finite spectral triple $(A_{\text{int}}, H_{\text{int}}, D_{\text{int}})$ of UHM (theorem T-53 [T]) satisfies the premises of the Chamseddine–Connes–Marcolli theorem:

1. Algebra $A_{\text{int}} = \mathbb{C} \oplus M_3(\mathbb{C}) \oplus M_3(\mathbb{C})$ — corresponds to NCG Standard Model.
2. Dirac operator $D_{\text{int}}$ — finite-dimensional, self-adjoint — corresponds.
3. Higgs field as internal fluctuation $A_{\text{int}}$: $H = A + JAJ^{-1}|_{E\text{-}U}$ — corresponds.

Step 2 (Spectral action). The spectral action $S = \mathrm{Tr}(f(D/\Lambda))$ (see quantum gravity) expands as:

$S = f_4 \Lambda^4 a_0 + f_2 \Lambda^2 a_2 + f_0 a_4 + O(\Lambda^{-2})$

The coefficient $a_4$ contains the term $\mathrm{Tr}(D_{\text{int}}^4)$, generating the quartic Higgs potential.

Step 3 (Computation). From sectoral values (T-61, unique vacuum [T]):

$\mathrm{Tr}(D_{\text{int}}^2) \approx 6\omega_0^2\varepsilon_0^2, \qquad \mathrm{Tr}(D_{\text{int}}^4) \approx 6\omega_0^4\varepsilon_0^4 + \text{sectoral corrections}$

Step 4 (RG evolution). The bare $\lambda_4(\Lambda)$ is too large. RG running from $\Lambda$ to $v_{\text{EW}}$:

$\lambda_4(v) = \lambda_4(\Lambda) + \frac{1}{16\pi^2}\left(24\lambda_4^2 - 6y_t^4 + \ldots\right) \ln\frac{v}{\Lambda}$

At $y_t \approx 1$ (quasi-IR fixed point [T]): RG brings $\lambda_4$ to the observed $\approx 0.13$ from $\lambda_4(\Lambda) \approx 0.20$ [C] — standard Shaposhnikov–Wetterich result (2010). $\blacksquare$

Status: [C] — $\lambda_4$ determined through spectrum $D_{\text{int}}$ + RG. Parameter $f_0$ is canonically determined [T] (T-70). The conditionality [C] remains only for the numerical value — depends on exact sectoral $\varepsilon_i$.

Theorem 4.1 (Higgs mass) [C]

[C] Conditional

The formula for the Higgs mass contains $\lambda_4$, determined from the spectral action (theorem on Higgs quartic [C]), and the octonionic correction from $V_3$. Parameter $f_0$ is canonically determined [T] (T-70); conditionality [C] — only numerical value through $\varepsilon_i$.

Theorem. The Higgs mass is determined as the second derivative of the potential $V_{EU}$ at the minimum:

(a) Formula:

$M_H^2 = 2\lambda_4 v^2 + \frac{3\lambda_3^2 \bar{A}^2}{4\mu^2}$

First term — standard (from $V_4$). Second — octonionic correction from $V_3$.

Proof. The potential $V_\text{Gap}$ projects onto the $E$-$U$ channel:

$V_{EU}(\gamma_{EU}) = \mu^2 |\gamma_{EU}|^2 + \lambda_4 |\gamma_{EU}|^4 + \lambda_3 \bar{A} |\gamma_{EU}|^3 \cos(\text{phase})$

At $\mu^2 < 0$: minimum at $|\gamma_{EU}| = v \neq 0$.

Higgs mass = second derivative of $V_{EU}$ at the minimum:

$M_H^2 = \frac{\partial^2 V_{EU}}{\partial |\gamma_{EU}|^2}\bigg|_{v} = 2\lambda_4 v^2 + \frac{3\lambda_3^2 \bar{A}^2}{4\mu^2}$

$\blacksquare$

Free parameters

$\lambda_4$ and $f_0$ are two free parameters of the spectral action, not derivable from $\Omega^7$. The prediction of $M_H$ is parametric, not absolute.

4.1 Octonionic correction

Theorem 4.2 (Deviation from SM) [C]

[C] Conditional

The quantitative estimate $\delta\lambda/\lambda_\text{SM} \sim O(10^{-2}\text{--}10^{-3})$ depends on the octonionic parameters of the Gap potential ($\lambda_3$, $\bar{A}$, $\mu$). Parameter $\lambda_4$ is determined from the spectral action [C]; the octonionic correction is an additional contribution.

Theorem. The octonionic structure predicts a deviation from the standard Higgs mass relation:

(a) In SM: $M_H^2 = 2\lambda v^2$ (one parameter $\lambda$).

(b) In UHM: $M_H^2 = 2\lambda_4 v^2 + \delta M_H^2$, where:

$\delta M_H^2 = \frac{3\lambda_3^2 \bar{A}^2}{4\mu^2} \approx \frac{3 \cdot (73.8)^2 \cdot (0.047)^2}{4 \cdot 16.6} \approx 5.5$

(c) Octonionic correction to $\lambda_\text{eff} = \lambda_4 + \delta\lambda$:

$\frac{\delta\lambda}{\lambda_4} = \frac{3\lambda_3^2 \bar{A}^2}{8\lambda_4 \mu^2 v^2}$

(d) Falsifiable prediction: with improved precision in measuring the Higgs triple vertex (HL-LHC, FCC), the effective self-coupling $\lambda_\text{eff}$ differs from the SM value by:

$\frac{\delta\lambda}{\lambda_\text{SM}} \sim \frac{\lambda_3^2 \bar{A}^2}{\lambda_4 \mu^2} \sim O(10^{-2} \text{--} 10^{-3})$

— at the percent level, potentially accessible at FCC-hh.

4.2 Origin of the octonionic correction

The octonionic correction from $V_3$ has the following structure:

1. $V_3 = \lambda_3 \sum_{(i,j,k) \notin \text{Fano}} |\gamma_{ij}||\gamma_{jk}||\gamma_{ik}| \sin(\theta_{ij} + \theta_{jk} - \theta_{ik})$ — the cubic octonionic potential.

2. Projection onto the $E$-$U$ channel gives the contribution $\lambda_3 \bar{A} |\gamma_{EU}|^3$, where $\bar{A}$ is the average product of coherence moduli in other channels.

3. This cubic term is absent in the standard model and is a direct consequence of the octonionic ($\mathbb{O}$) structure of the theory.

4. Physically: $V_3$ is responsible for the breaking of $PT$-symmetry (the Gap arrow), and its contribution to the Higgs mass connects the electroweak sector to the global octonionic structure of the dimension space.

4.3 Connection to the Fano selection rule and octonionic structure constants

[T] Theorem

The Yukawa coupling of generation $k_n$ to the Higgs field $\gamma_{EU}$ is proportional to the octonionic structure constant $f_{k_n,E,U}$, which is nonzero if and only if $(k_n,E,U)$ forms a Fano line.

The octonionic correction to the Higgs mass is directly connected to the Fano selection rule. The tree-level Yukawa coupling of generation $k_n$ to the Higgs field is determined by:

$y_n^{(\text{tree})} = g_W \cdot \varepsilon_{k_n, E, U}^{\text{Fano}} \cdot \sin\!\left(\frac{2\pi k_n}{7}\right) \cdot |\gamma_{\text{vac}}^{(EU)}|$

where $\varepsilon_{ijk}^{\text{Fano}} = 1$ if $(i,j,k)$ is a Fano line, and $0$ otherwise. Equivalently: $y_{abc}^{(\text{tree})} \propto f_{abc}$, where $f_{abc}$ is the structure constant of the algebra $\mathbb{O}$, associated with the multiplication table: $e_a e_b = f_{abc} \, e_c + \delta_{ab}$.

For the three generations $k \in \{1, 2, 4\}$:

Generation	$k$	Triple $(k,E,U)$	Fano line?	$f_{k,5,6}$	$y^{(\text{tree})}$
Third (heavy)	$1$	$(1,5,6)$	Yes: $\{A,E,U\}$	$1$	$\neq 0$
Second	$2$	$(2,5,6)$	No	$0$	$= 0$
First	$4$	$(4,5,6)$	No	$0$	$= 0$

Consequence for Higgs mass. The Higgs mass is generated by a loop with a virtual $t$-quark (the only fermion with $y^{(\text{tree})} \neq 0$). Radiative corrections to $M_H^2$ from the top quark:

$\delta M_H^2 \Big|_{\text{top}} = -\frac{3 y_t^2}{8\pi^2} \Lambda^2 + \ldots$

In UHM the role of the UV cutoff $\Lambda$ is played by the scale $\mu_\text{phys}$ — the physical unit of Gap coherence. The octonionic correction from $V_3$ partially compensates the quadratic divergence, since the cubic potential modifies the vacuum structure. This is the germ of a solution to the hierarchy problem from within the Gap formalism.

4.4 Parity breaking from $V_3$ and stability of the chiral vacuum

[T] Theorem

Dynamical stability of the chiral vacuum is proved from existing [T]-results.

The cubic potential $V_3$ (and the associated orientational $V_\varphi$-contribution) ensures dynamical stability of chiral distinction in the $E$-$U$ channel:

(a) In the $\bar{3}$-sector $V_\varphi$ takes the form:

$V_\varphi^{(\bar{3})} = \lambda_\varphi \cdot \varphi_{LEU} \cdot |\gamma_{LE}||\gamma_{EU}||\gamma_{LU}| \cdot \sin(\theta_{LE} + \theta_{EU} - \theta_{LU})$

(b) $PT$-property: $V_\varphi \to -V_\varphi$ under $PT$-transformation ($\theta \to -\theta$). This creates an asymmetry of the minimum of $V_\text{Gap}$ in the $E$-$U$ channel.

(c) Energy difference between the left ($\text{Gap}(E,U) = 0$) and right ($\text{Gap}(E,U) \neq 0$) fermionic vacua:

$\Delta V = V_\varphi^{(\pi)} - V_\varphi^{(0)} = 2\lambda_\varphi |\gamma_{LE}||\gamma_{LU}| \cdot |\gamma_{EU}|$

(d) Without $V_3$, chirality would be unstable to radiative corrections. The $PT$-odd potential prevents relaxation of a left-handed fermion into a right-handed one, ensuring the observed parity violation in weak interactions.

Proof:

Step 1. $V_3$ is the unique $PT$-odd term in $V_{\mathrm{Gap}}$ [T] (T-99, step 2). It distinguishes chiral vacua: $\theta = 0$ and $\theta = \pi$ give different signs of the cubic combination $\sin(\theta_{ij} + \theta_{jk} - \theta_{ik})$.

Step 2. The vacuum of $V_{\mathrm{Gap}}$ is unique with positive definite Hessian [T] (T-64). No flat directions → the chiral minimum is non-degenerate.

Step 3. Topological barrier [T] (T-69): $\Delta V \geq 6\mu^2 > 0$ prevents tunneling between chiral vacua.

Conclusion. $V_3$ selects the chiral vacuum (step 1), the Hessian ensures local stability (step 2), the topological barrier — global protection from tunneling (step 3). $\blacksquare$

5. Connection to SM gauge structure

5.1 Gauge boson mass hierarchy

Theorem 5.1 (Mass hierarchy from Gap hierarchy) [T]

[T] Theorem

The gauge mass hierarchy follows from the Fano–electroweak (FE) construction [T]: uniqueness of the pair $(E,U)$ is proved from $\kappa_0$ [T] — see uniqueness theorem. The identification of Gap sectors with SM gauge groups is determined uniquely.

Theorem. The scale hierarchy of gauge bosons is determined by the Gap hierarchy of the vacuum:

(a) Massless ($\text{Gap} = 0$ in the corresponding sector):

• Gluons: $\text{Gap} = 0$ in $3$-to-$\bar{3}$ → confinement (nonlinear dynamics as $\text{Gap} \to 0$)
• Photon: $\text{Gap} = 0$ for the diagonal $U(1)_\text{EM}$ combination

(b) Electroweak scale ($\text{Gap} \sim 10^{-17}$ from Planck):

• $W^\pm$, $Z$: $\text{Gap}(E,U) \sim v/M_\text{Planck} \sim 10^{-17}$

(c) Planck scale:

• $G_2$-extra: $\text{Gap} \sim 1$ → mass $\sim M_\text{Planck}$

Corollary. The mass hierarchy $M_\gamma = 0 \ll M_W \ll M_{G_2}$ follows from the Gap hierarchy $0 \ll 10^{-17} \ll 1$ in the corresponding coherence sectors.

Note

In early versions this section included the GUT scale with $X$, $Y$ leptoquarks ($M_X \sim v_\text{GUT}$), based on the embedding $SU(5) \subset SU(6)$ from the 42D Page–Wootters extension. Within the Fano–electroweak (FE) construction the electroweak sector is derived directly from the Fano geometry of the $\bar{3}$-sector without invoking $SU(5)$-GUT, and the prediction of $X$, $Y$-leptoquarks is not a consequence of the (FE)-framework. The question of the existence of a GUT scale remains open.

5.2 Complete table of gauge fields

Field	Group	Number	Mass	Gap source	Status
Gluons $g$	$SU(3)_C$	8	0 (confinement)	$\text{Gap}_{3\to\bar{3}} \approx 0$	[T]
$W^\pm$, $Z$	$SU(2)_L$	3	$M_W$, $M_Z$	$\text{Gap}(E,U) \sim 10^{-17}$	[T]
Photon $\gamma$	$U(1)_\text{EM}$	1	0	Diagonal $U(1)$	[T]
$G_2$-extra	$G_2/SU(3)$	6	$M_{G_2} \sim \mu_\text{phys}$	$\text{Gap}^{(O)} \sim 1$	[C]

Note on leptoquarks

In the previous version the table included $X$, $Y$-leptoquarks ($SU(5)/\text{SM}$, 12 fields, $M_X \sim v_\text{GUT}$). These particles are specific to the $SU(5)$-GUT embedding and do not follow from the Fano–electroweak (FE) construction. They have been removed from the main table.

5.3 Electroweak sector: Fano–electroweak (FE) construction [T]

Replacement of the former SU(6) derivation

In early versions the electroweak sector was derived from the Page–Wootters extension $\mathcal{H}_\text{total} = \mathbb{C}^7 \otimes \mathbb{C}^6 = \mathbb{C}^{42}$, where the $6D$-factor carried $SU(6)$-symmetry, and via the embedding $SU(5) \subset SU(6)$ (analogue of the Georgi–Glashow model) $SU(2)_L \times U(1)_Y$ was extracted. This approach had a rank problem ($\text{rank}(G_2) = 2 < \text{rank}(SM) = 4$) and led to spurious predictions ($X$, $Y$-leptoquarks).

The Fano–electroweak (FE) construction replaces the $SU(6)/SU(5)$ derivation, extracting the electroweak structure directly from the geometry of the $\bar{3}$-sector of the Fano plane.

In the (FE)-construction the electroweak sector $SU(2)_L \times U(1)_Y$ arises from the structure of the $\bar{3}$-sector $\{L, E, U\}$ of the plane $\mathrm{PG}(2,2)$:

(a) $SU(2)_L$ is identified with the group acting on the doublet $(E, U)$ at $\text{Gap}(E,U) = 0$. The uniqueness of the Higgs line $\{A, E, U\}$ [T] guarantees unambiguity in the choice of the electroweak channel.

(b) $U(1)_Y$ is determined by the total Gap in the $O$-sector (see section 3.3):

$Y = \frac{1}{3}\left(\sum_{i \in 3} \text{Gap}(O,i) - \sum_{j \in \bar{3}} \text{Gap}(O,j)\right)$

(c) $SU(3)_C$ — still from the $G_2$-stabilizer ($G_2 \supset SU(3)$, decomposition $14 \to 8+3+\bar{3}$) [T].

Advantages of (FE) over $SU(6)/SU(5)$:

• Does not require additional structure ($SU(6)$ from 42D)
• Does not generate $X$, $Y$-leptoquarks as a mandatory prediction
• The electroweak sector is tied to the same Fano geometry as the Higgs mechanism
• The rank problem ($\text{rank}(G_2) = 2 < 4 = \text{rank}(SM)$) is resolved: the missing generators are taken from the HS-projection of the $\bar{3}$-sector [T], not from an external $SU(6)$

6. Falsifiable predictions

6.1 Deviation of the Higgs triple vertex [C]

[C] Conditional

The quantitative prediction depends on the octonionic parameters of the Gap theory ($\lambda_3$, $\bar{A}$) and the spectral action parameter $f_0$.

Prediction. The effective Higgs self-coupling differs from the SM value:

$\frac{\delta\lambda}{\lambda_\text{SM}} \sim O(10^{-2} \text{--} 10^{-3})$

Test: HL-LHC (precision $\sim 50\%$ on triple vertex), FCC-hh (precision $\sim 5\%$).

6.2 Connection of Higgs mass to octonionic structure [C]

In the SM the Higgs mass $m_H \approx 125$ GeV is a free parameter. In UHM:

$m_H^2 = 2\lambda_4 v^2 + \delta m_H^2(\lambda_3, \bar{A}, \mu)$

The first term is determined by the spectral action (theorem on Higgs quartic [C]). The octonionic correction $\delta m_H^2$ connects the Higgs mass to the octonionic potential parameters. When $f_0$ is fixed from other observables (quark masses, CKM elements), the Higgs mass becomes computable — this is a potentially powerful prediction.

6.3 Mass hierarchy problem [H]

Corollary. The mass hierarchy problem ($M_W / M_\text{Planck} \sim 10^{-17}$) reduces to the question: why does the Gap-vacuum have such different values in different sectors? Answer: sectoral values $\varepsilon_X$ are determined by the unique minimum of $V_{\text{Gap}}$ (theorem on unique vacuum [T]).

Hypothetical solution via RG evolution: at the Planck scale all $\text{Gap} \sim O(1)$ (democratic initial condition). RG flow from Planck to IR: different sectors flow with different anomalous dimensions:

Sector	Anomalous dimension	Gap at IR scale
$3$-to-$\bar{3}$ (color)	$\Delta_{3\bar{3}} = 0$ (marginal)	$\sim 0$ (confinement)
$\bar{3}$-to-$\bar{3}$ (EW)	$\Delta_{\bar{3}\bar{3}} = \Delta_3 = 5/42$	$\sim 10^{-17}$ (EW scale)
$O$-to-$3$ (gravity)	$\Delta_{O3} \gg 1$ (IR-relevant)	$\sim 1$ (Planck scale)

The difference in anomalous dimensions is determined by Fano combinatorics: the number of Fano lines passing through a pair $(i,j)$ affects $\Delta_{ij}$.

6.4 Dynamical dark energy [P]

Open program: the connection between the RG scale of Gap and the cosmological evolution $H(t)$ has not been established from axioms A1–A4. The estimate $w_a \sim -10^{-2}$ is a motivated ansatz, not a prediction. Status: [P].

From the nonlinear Gap-gravity system it follows: the dark energy equation of state depends on the cosmological epoch. The Higgs sector (Gap in $\bar{3}$-to-$\bar{3}$) contributes to the effective cosmological constant:

$w(z = 0) = -1 + \delta w, \quad \delta w = \frac{\kappa \cdot \langle|\gamma|^2\rangle}{V_\text{Gap}} \sim \frac{\kappa \cdot \epsilon^2}{\mu^2 \text{Gap}^2}$

The numerical estimate $w_a \sim -10^{-2}$ is testable by Euclid, Roman, DESI missions, but its derivation from Gap axioms remains an open program.

6.5 Chirality tunneling rate [T]

Theorem T-185b [T]: Chirality stability prediction

The chiral vacuum is stable against tunneling with a lifetime vastly exceeding the age of the universe:

$\tau_{\text{chiral}} \sim \frac{1}{\mu} \exp\!\left(\frac{B}{\hbar}\right) \gg \tau_{\text{universe}} \approx 4.4 \times 10^{17}\;\text{s}$

where $B \geq \pi\sqrt{12}\,\mu \approx 10.88\,\mu$ is the WKB bounce action through the barrier $\Delta V \geq 6\mu^2$ (T-69 [T]).

Derivation. The WKB tunneling rate between the chiral vacua $\theta = 0$ and $\theta = \pi$:

$\Gamma_{\text{tunnel}} = \mu \cdot \exp\!\left(-\frac{B}{\hbar}\right), \quad B = \int_0^{\pi} \sqrt{2\Delta V(\theta)}\,d\theta \geq \pi\sqrt{2 \cdot 6\mu^2} = \pi\sqrt{12}\,\mu$

In physical units with $\mu \sim M_{\text{Planck}}$: the exponent $e^{10.88 \cdot M_{\text{Planck}} / T_{\text{eff}}}$ is astronomically large for any $T_{\text{eff}} \ll M_{\text{Planck}}$.

Falsifiable prediction. Observation of spontaneous chirality flipping (a right-handed neutrino appearing from a left-handed one without a mass insertion) at any sub-Planckian energy would falsify the topological protection theorem T-69 [T] and the cubic potential $V_3$ (T-99 [T]).

Status. [T] — follows from T-69 [T] (topological barrier), T-64 [T] (unique vacuum), T-99 [T] ($V_3$ is the unique $PT$-odd term).

7. Can UHM predict the Higgs mass?

7.1 Problem statement

Experimental value: $M_H^{\text{exp}} = 125.09 \pm 0.24$ GeV. In the Standard Model $M_H$ is a free parameter. In Chamseddine–Connes noncommutative geometry (NCG) the Higgs mass is computed from the spectral triple. Question: can UHM do the same?

7.2 Derivation chain for $M_H$ in UHM

The full chain from axioms to $M_H$ consists of five links:

Link	Statement	Status	Dependency
(1) Spectral triple	$(A_{\text{int}}, H_{\text{int}}, D_{\text{int}})$ exists, KO-dim = 6	[T] (T-53)	Axioms
(2) Spectral action	$S = \mathrm{Tr}(f(D_A/\Lambda))$ expands in Seeley–DeWitt series	[T] (T-65)	(1)
(3) $f_0$ canonically determined	$f_0 = \Gamma_{\text{eff}} / (7\Lambda^4)$ through Gap theory vacuum	[T] (T-70)	(2) + unique vacuum T-64 [T]
(4) $\lambda_4$ from $D_{\text{int}}$ + RG	$\lambda_4 = \frac{\pi^2}{2f_0\Lambda^4} \cdot \frac{\mathrm{Tr}(D_{\text{int}}^4)}{[\mathrm{Tr}(D_{\text{int}}^2)]^2}$, RG: $\Lambda \to v_{\text{EW}}$	[C]	(3) + numerical $\varepsilon_i$
(5) $M_H$ from potential	$M_H^2 = 2\lambda_4 v^2 + \delta M_H^2(\lambda_3, \bar{A}, \mu)$	[C]	(4) + octonionic correction

Verdict: [C] — conditional on numerical values of sectoral parameters $\varepsilon_i$ determining the spectrum $D_{\text{int}}$.

7.3 Why $g_4^* = 4\pi^2/63$ is NOT the Higgs quartic

Common error

The Wilson–Fisher fixed point of the Gap theory $g_4^* = 4\pi^2/63 \approx 0.063$ is not the Higgs quartic $\lambda_H$ of the Standard Model. The naive identification gives $M_H = \sqrt{2 g_4^*} \cdot v \approx 87$ GeV — an incorrect result.

Distinction:

	Gap quartic $g_4^*$	Higgs quartic $\lambda_H$
Theory	(0+1)D Gap on $(S^1)^{21}$	4D QFT on $M^4$
Number of fields	21 coherences	1 doublet (4 real fields)
Factor in $\beta$	63 (from combinatorics $\binom{21}{2} \cdot 3$)	$\sim 24$ (loop with $W$, $Z$, $t$)
IR value	$4\pi^2/63 \approx 0.063$	$\approx 0.13$ (from $M_H = 125$ GeV)
Origin	Wilson–Fisher RG fixed point of Gap	Spectrum $D_{\text{int}}$ + SM RG running

Connection between them: $g_4^*$ determines the IR value of the quartic coupling of the Gap potential $V_{\text{Gap}}$. The Higgs quartic $\lambda_H$ is determined by the projection of $V_{\text{Gap}}$ onto the $E$-$U$ channel via the spectral action, and then evolves under 4D SM RG equations.

7.4 Comparison with Chamseddine–Connes NCG

In the Chamseddine–Connes–Marcolli (CCM) approach the history of predicting $M_H$ went through three stages:

(a) Tree level (CCM 2007): $M_H = \sqrt{8\lambda_H} \cdot v$ with $\lambda_H$ from $\mathrm{Tr}(D_{\text{int}}^4)/[\mathrm{Tr}(D_{\text{int}}^2)]^2$. With top quark dominance:

$M_H^{(\text{tree})} \approx \frac{M_t}{\sqrt{2}} \approx \frac{173}{\sqrt{2}} \approx 122 \text{ GeV}$

However, without RG correction the exact Chamseddine–Connes formula (2012) gave $\sim 170$ GeV — an incorrect result.

(b) With RG running (Shaposhnikov–Wetterich 2010): RG evolution from $\Lambda_{\text{GUT}}$ to $v_{\text{EW}}$ reduces $\lambda_H(\Lambda) \approx 0.20$ to $\lambda_H(v) \approx 0.13$, giving $M_H \approx 125$ GeV. But this fixes $\Lambda_{\text{GUT}}$, not predicts it.

(c) With scalar field $\sigma$ (Chamseddine–Connes–van Suijlekom 2013): introduction of the $\sigma$-field from internal fluctuations changes the boundary condition at $\Lambda$, leading to $M_H \approx 126$ GeV — the first correct prediction from NCG.

UHM position: the octonionic correction from $V_3$ plays a structurally analogous role to the $\sigma$-field in CCM-2013. The cubic potential $V_3$ modifies the effective Higgs potential, shifting the tree-level value of $M_H$ closer to the experimental value. However, the exact numerical value of the correction depends on vacuum parameters $\varepsilon_i$, which have not yet been computed.

7.5 What is needed for a full prediction

For converting $M_H$ from [C] to [T] one needs:

1. Numerical solution of vacuum equations on $(S^1)^{21}/G_2$: determine exact values of $\varepsilon_i$ for all 5 orbital parameters (task C16 in the status registry).

2. Computation of $f_0$: substitute $\varepsilon_i$ into the canonical formula T-70 and find the numerical value of $f_0$.

3. Computation of $\mathrm{Tr}(D_{\text{int}}^4)$: determine $\lambda_4(\Lambda)$ from the spectrum $D_{\text{int}}$ with known $\varepsilon_i$.

4. SM RG running: evolution $\lambda_4(\Lambda) \to \lambda_4(v_{\text{EW}})$ — standard procedure containing no additional free parameters.

5. Octonionic correction: compute $\delta M_H^2$ from Gap parameters.

All formulas are defined [T]; the task is computational [C]. This is analogous to the situation in lattice QCD, where the formulas are exact, but numerical predictions require computation.

7.6 Final assessment [C]

[C] Conditional

UHM determines the Higgs mass through chain (1)–(5), in which links (1)–(3) have status [T], and links (4)–(5) — status [C] due to incomplete computation of sectoral parameters $\varepsilon_i$. No additional postulates or hypotheses are required: the task is purely computational.

Summary:

• Can UHM in principle predict $M_H$? Yes — the formulas are fully determined.
• Does it predict now? No — requires solving task C16 (numerical computation on $(S^1)^{21}/G_2$).
• Naive $g_4^* \to M_H$: incorrect ($g_4^* \neq \lambda_H$), gives $\sim 87$ GeV.
• Status: [C] — conditional on computation of $\varepsilon_i$.
• Comparison with NCG: UHM reproduces the CCM structure, but adds the octonionic $V_3$-correction, analogous to the $\sigma$-field of Chamseddine–Connes–van Suijlekom.
