Baryon asymmetry of the universe in the minimal Standard Model

We calculate the baryon asymmetry of the Universe which would arise during a first-order electroweak phase transition due to minimal-standard-model processes. It agrees in sign and magnitude with the observed baryonic excess, for reasonable Kobayashi-Maskawa parameters and mt in the expected range, and plausible values of bubble velocity and other high temperature effects. © 1993 The American Physical Society.
