Electroweak Breaking: Mapping from Internal Coset to External Mass Phenomena (Preliminary Draft)

Based on the internal–external dichotomy ontology, this paper reinterprets electroweak symmetry breaking. The core thesis is that electroweak breaking is not a historical spontaneous symmetry breaking, but the permanent projection of the internal SU(3) coset geometry onto external spacetime. The internal geometry contains no Higgs field, mass terms, or Yukawa couplings; the Higgs doublet, W/Z masses, fermion masses, and the Weinberg angle are all external phenomena emerging when the observer reads the internal structure through the SU(3) coset template. The radial mode of the coset corresponds to the Higgs boson, the three angular coordinates are eaten by W/Z as longitudinal polarisation modes, and the vacuum expectation value originates from the ground‑state configuration of the coset squared norm. The Weinberg angle is a geometric measure of the projection asymmetry of the coset; the photon is massless because its projection vanishes. The framework excludes X/Y bosons, predicts that the proton may be absolutely stable, and reduces the Standard Model Higgs potential and Yukawa couplings to external parametrisations of the coset geometry.
