The Koide formula: K = (m_e + m_μ + m_τ) / (√m_e + √m_μ + √m_τ)² = 2/3
Holds to 0.01%. For 40 years, unexplained.
New paper: derives K = 2/3 from S⁷/Z₃³ geometry. SU(3) Cartan normalization gives β/α = √3, forcing K = 2/3 exactly.
Same framework predicts Cabibbo angle θ_C = 12.99° (observed: 13.04°, 0.4% error).
Worth a look.

Fermion Mass Geometry: Deriving Koide K=2/3 and the Cabibbo Angle from S^7/Z_3^3 Orbifold Geometry
Fermion Mass Geometry (Version 3) Derives the Koide formula K = 2/3 for charged leptons from S7/Z_33 orbifold geometry. The sqrt(3) ratio beta/alpha emerges from SU(3) -> SU(2) x U(1) Cartan normalization. Electron smallness comes from enhancement point perturbations with Koide-locked projection (cos^2(gamma) ~ 0.155). Cabibbo angle theta_C = 45 deg / sqrt(12) = 12.99 deg (PDG: 13.04 deg). Quarks modeled by distortion operator L(s) with s = cos(phi) from Z_2 involution, yielding "elliptical Koide" formula.
