Geometric Standard Model: Unified Particle Spectrum from Topological Parameters

We present a complete geometric formulation of the Standard Model with only four fundamentalparameters derived from topological phase transitions. The model predicts masses of all 61 known particles with mean accuracy 0.3%, gauge couplings, and exotic states. Key results: (1) Quark masses from curvature integrals (2) Lepton masses via torsion vacuum expectation (3) Confinement as π1(T 2)̸ = 0 topological constraint. Experimental verification shows< 1% deviation for hadrons and predicts stable tetraquark T ++ at 5270 ± 40 MeV.
