Baryogenesis

La baryogénèse se serait produite après l'inflation (en beige), mais bien avant la première seconde suivant le Big Bang. Elle se situerait dans les parties jaune-orange du schéma ci-haut.

Dans ce diagramme de Feynman, un électron et un positron s'annihilent en produisant un photon virtuel qui devient une paire quark-antiquark, puis émettent un gluon. (Le temps va de gauche à droite, et la dimension spatiale va de haut en bas.)

In physical cosmology, baryogenesis is the generic term for the hypothetical physical processes that produced an asymmetry (imbalance) between baryons and antibaryons produced in the very early universe. The baryonic matter that remains today, following the baryonic-antibaryonic matter annihilation, makes up the universe.
