Derivation of Baryon Masses from Confinement Geometry and Relativistic Kinematics

The mass of any light baryon (uu, dd, ss quarks) is derived without fitting parameters from five fundamental inputs: QCD scale ΛQCD=200ΛQCD=200 independently via asymptotic freedom in deep inelastic scattering (high-Q2Q2 regime where hadrons do not yet form). Geometric factor π/2=1. 5708π/2=1. 5708Arising from equilateral triangle topology of three-body confinement (90° projection angle for ground state). Quark momentum pc=ΛQCD⋅π/2=314. 16=ΛQCD⋅π/2=314. 16 consequence of (1) and (2) — no fitting. Current quark massesmu=2. 16=2. 16, md=4. 67=4. 67, ms=93. 0=93. 0 exclusively on light meson spectra (π±π±, K±K±), never on baryons.
