Matter–Antimatter Asymmetry & Baryogenesis: Physical Mechanisms

The observable universe contains far more matter than antimatter, even though known microscopic laws often treat matter and antimatter nearly symmetrically. Baryogenesis links cosmology to neutrino physics, high-energy particle theory, and searches for new CP violation.

If reactions in the early universe violated baryon number and CP symmetry while occurring out of equilibrium, slightly more baryons than antibaryons could survive.
