Parameter-Free Derivation of 𝑚𝑝/𝑚𝑒 and 𝛼 from Spectral Geometry on 𝑇5 with SU(3)

We derive the proton-to-electron mass ratio and the fine-structure constant from a single geometric structure — with zero free parameters. Main Results m_p/m_e = 6π⁵(1 + α²/√8) = 1836.15268 — accuracy: 0.002 ppm (CODATA: 1836.15267) −2 ln α = π² − 4α + c₂α² — accuracy: 0.009 ppm (CODATA: α = 1/137.036) Δm(n−p)/m_e = 8/π − 2α — neutron-proton mass splitting (354 ppm) Framework The computation uses spectral geometry on the isotropic five-torus T⁵ with SU(3) gauge field. The Hosotani mechanism stabilizes the Wilson-line vacuum at a = 1/2 (Ramond boundary conditions). The instanton action S₀ = π² and the Weyl group order |W(SU(3))| = 6 combine to give the exact identity 6π⁵ via the Weyl integration formula. No parameters are adjusted — all inputs are topological or group-theoretic. Proof Architecture: 4-Tier Classification (26 results, no open problems) Tier 0 (9 results): Known, cited — Hosotani mechanism, Georgi-Glashow sin²θ_W = 3/8, Epstein zeta, Clifford algebra d_S = 4, Hurwitz ζ', quark charges ΣQ² = 1, R-independence, π⁷-bridge algebra. Tier 0+1 (5 results): Known methods, our specific application — Ramond BC from S₅-isotropy, c₂ = 5/2 ln 2 − 3/8, Gilkey-Seeley G_e/G_p = 6, Atiyah-Singer ind(D_p) = 6, the Matching Principle (Connes 1994). Tier 1 (12 results): Genuinely new, proved here — Weyl identity 6π⁵, d = 5 uniqueness theorem, bootstrap uniqueness, c₃ independent formula (6 ppm), δ_EW = 0 (exact), spectral entanglement identity, gap decomposition theorem, Weyl orbit theorem, β* = 13.6 analytical, 1/√8 from 3 routes, toy model d = 1…5, GPU verification to 50 digits. Tier 2/3: None remaining. All formerly open problems resolved in v55. 33 Parameter-Free Consequences (V1–V33) Including: V1: m_p/m_e = 1836.15268 (0.002 ppm) ✓ V3: α = 1/137.036 (0.009 ppm) ✓ V22: θ_QCD = 0 exactly (no axion needed) — testable via nEDM V23: Proton stable (τ > 10¹⁰⁰⁰ yr) — testable at Hyper-K V30: N_gen = N_c = 3 ✓ V31: Neutrinos are Dirac particles — neutrinoless double beta decay (0νββ) is FORBIDDEN. Testable at LEGEND/nEXO/CUPID (2027–2028). A single 0νββ event would falsify SFST. V32: Σm_ν ≈ 3m_e α² ≈ 0.08 eV — within Planck/KATRIN window Standard Physics as Limits Maxwell equations and Einstein equations emerge as Kaluza-Klein zero-mode reductions (Tier 0). The Weinberg angle sin²θ_W = 3/8 at the compactification scale reproduces the Georgi-Glashow (1974) prediction. Known Limitations (stated explicitly) The Matching Principle (det'/det' → m_p/m_e) is Tier 0+1: standard method (Connes 1994), not derived from first principles for this specific bundle. Lepton mass hierarchy (μ, τ) not predicted. Absolute energy scale (R in Planck units) not determined.
