Conditional Matter-Antimatter Annihilation

This deposit includes the main manuscript and supplementary material for the article “Conditional Matter-Antimatter Annihilation: A Minimal Scalar Extension of the Standard Model” by Ernest Darell Zermeno. The main text presents a structural suppression mechanism for particle-antiparticle annihilation based on a new scalar mediator and a misalignment parameter θ, predicting a relic fraction of metastable z-states consistent with dark matter abundance. The supplementary document provides detailed derivations of the suppression function, cosmological freeze-out integrals, GEANT4 implementation, renormalization group equations, and an extended categorical interpretation of matter-antimatter duality. All theoretical predictions are falsifiable with current experiments. For correspondence: [email protected]
