Sakharov conditions are a set of three criteria proposed by Andrei Sakharov in 1967 that are necessary for baryogenesis, the process that led to the matter-antimatter asymmetry in the universe. These conditions are baryon number violation, C and CP violation, and a departure from thermal equilibrium, all of which are essential to explain why there is more matter than antimatter in the universe today.

Baryogenesis is the theoretical process that attempts to explain the imbalance between matter and antimatter in the universe. It involves mechanisms that violate baryon number conservation, CP symmetry, and thermal equilibrium to produce a surplus of baryons over antibaryons after the Big Bang.

baryogenesis

Matter-antimatter asymmetry refers to the observed imbalance between matter and antimatter in the universe, where matter vastly outnumbers antimatter despite theories suggesting they should have been created in equal amounts during the Big Bang. This asymmetry is a fundamental question in physics and has implications for understanding the evolution of the universe and the laws governing particle interactions.

matter-antimatter asymmetry

Baryon number violation refers to theoretical processes in which the conservation of baryon number is not upheld, allowing baryons to transform into other particles. This concept is crucial for explaining phenomena like baryogenesis, which accounts for the matter-antimatter asymmetry in the universe.
