P16: [Proof Group D] STRANGE QUARK — Z2 MIXING ANGLE PROOF

STRANGE QUARK — Z2 MIXING ANGLE PROOF Prove that the strange quark mass is parameterized by a Z2 mixing angle theta_s between the D-anchor (null-cone) and v+-anchor (forward): m_s = cos^2(theta_s) * m_s(D) + sin^2(theta_s) * m_s(v+). Identify the algebraic origin of theta_s in Os — show it arises from the split of the imaginary basis into {e,f} pairs. Compare to PDG m_s = 93.4 MeV. Assess whether theta_s is derived or free. #SuperGrokTOE #StrangeQuark #Z2mixing
