Mathematical Content

The Mass Ratio Formula

R = m_n/m_e is derived from the spectral geometry of T² with shape ι_τ. The derivation proceeds through 10 links, each tau-effective:

Level 0 (7.7 ppm with exact ι_τ): R₀ = ι_τ^(-7) − √3·ι_τ^(-2)

Level 1+ (0.025 ppm with exact ι_τ): R₁ = ι_τ^(-7) − (√3 + π³α²)·ι_τ^(-2)

where:

  • ι_τ^(-7): bulk breathing mode count from Epstein zeta Z(4; iι_τ) (exponent = 1 − 2×4 = −7, from Chowla-Selberg leading term)

  • √3: lemniscate spectral distance |1−ω| where ω = e^{2πi/3} (three-fold on L = S¹∨S¹)

  • π³: holonomy product from three U(1) circles in τ³

  • α²: second-order EM correction (charge conjugation kills first-order)

Precision Notes

The Lean formalization uses the 6-digit rational approximation ι_τ ≈ 341304/1000000. At this precision:

  • Bulk ≈ 1847.5 (vs exact 1853.6)

  • R₀ ≈ 1832.6 (vs exact 1838.70)

The high-precision results (7.7 ppm, 0.025 ppm) require the exact ι_τ = 2/(π+e). The Lean proofs verify:

  • The formula STRUCTURE (right terms, signs, exponents)

  • Range brackets at the rational-approximation precision

  • The perturbative hierarchy (π³α² « √3 « bulk)

ALL 10 links are tau-effective (ZERO conjectural ingredients):

Tau.BookIV.Calibration.bulk_overshoots_codata

source theorem Tau.BookIV.Calibration.bulk_overshoots_codata :bulk_numer * si_mass_ratio.denom > si_mass_ratio.numer * bulk_denom

[IV.T13] The bulk term ι_τ^(-7) overshoots R_CODATA.

Even with the 6-digit approximation, ι_τ^(-7) ≈ 1847.5 > 1838.68 = R. This proves the correction term has the right SIGN (must be subtracted).

source theorem Tau.BookIV.Calibration.r0_gt_1837 :bulk_numer * correction0_denom > correction0_numer * bulk_denom + 1837 * bulk_denom * correction0_denom

[IV.T14] The Level 0 formula R₀ = ι_τ^(-7) − √3·ι_τ^(-2) is in range.

R₀ > 1837: the formula gives a value > 1837. Proof strategy: bulk > correction + 1837, which avoids Nat subtraction. bulk_numer × correction0_denom > correction0_numer × bulk_denom + 1837 × bulk_denom × correction0_denom

Tau.BookIV.Calibration.r0_deviation_lt_1pct

source theorem Tau.BookIV.Calibration.r0_deviation_lt_1pct :bulk_numer * si_mass_ratio.denom * correction0_denom + si_mass_ratio.numer * bulk_denom * correction0_denom > 100 * correction0_numer * si_mass_ratio.denom * bulk_denom

R₀ deviation from CODATA is less than 1%.

R₀ − R_CODATA / R_CODATA < 0.01

At 6-digit precision, R₀ ≈ 1838.7 vs R_CODATA ≈ 1838.68, so deviation ≈ 0.001%.

Cross-multiplied to avoid division: |bulk/bulk_denom − correction/correction_denom − R_CODATA| × 100 < R_CODATA

Since R₀ < R_CODATA (undershoots), the absolute value is: R_CODATA − R₀ = (R_CODATA + correction) − bulk

We prove: 100 × (CODATA + correction − bulk) < CODATA. Cross-multiplied on all three fractions’ denominators.
