   6# Electroweak Boson Mass Predictions — Machine-Verified

   8## Epistemological Status
   9
  10**QUARANTINED** from the certified surface: experimental values are imported
  11constants, not derived from RS.
  12
  13## Formula
  14
  15For the electroweak sector (B_pow = 1, r0 = 55):
  16  m(EW, r) = 2 × φ^{-5} × φ^{55} × φ^r / 10^6  [MeV]
  17           = 2 × φ^{50+r} / 10^6  [MeV]
  18
  19## Boson Rung Integers
  20
  21The W, Z, and Higgs bosons occupy specific rungs on the electroweak
  22phi-ladder. The Weinberg angle sin²θ_W = (3 − φ)/6 ≈ 0.2303 connects
  23W and Z masses: M_Z = M_W / cos(θ_W).
  24
  25## PDG 2024 Values
  26- W: 80,377 ± 12 MeV
  27- Z: 91,187.6 ± 2.1 MeV
  28- H: 125,250 ± 170 MeV
