hypothesized processes that could produce baryonic asymmetry, favoring matter (baryons) over antimatter (antibaryons)

In physical cosmology, baryogenesis is a process that is thought to have happened during the beginning of the universe.. It would create an imbalance in amount of matter and antimatter in the universe, called baryonic asymmetry. It is still a problem in modern physics.[1]
