The Chiral Seam: How a Single Geometric Boundary Generates the Standard Model of Particle Physics

Abstract The Standard Model of particle physics is the most precisely tested scientific theory in history. It predicts the behavior of fundamental particles to eleven decimal places of accuracy. Yet for all its predictive power, it is structurally incoherent. It contains twelve fermion masses spanning twelve orders of magnitude, several independent coupling constants, mixing angles, a handedness…
