Beauty for pedestrians toy models for CP violation and baryon asymmetry

摘要

Why are particles different from antiparticles. C and P Violation - 1956; CP Violation - 1964. Why so little new experimental information in thirty years. Where has all the antimatter gone. Toy models are presented showing: (1) How CPT and (Delta)I = 1/2 make life difficult in kaon physics by requiring equal K(sup (plus minus)) total widths and also equal partial widths to many exclusive channels. (2) How to understand and get around CPT restrictions. (3) How CP asymmetries can occur in exclusive partial widths and still add up to equal total widths. (4) Sakharov's 1966 scenario for how CP Violation + proton decay can explain baryon asymmetry (5) How B physics can help.
