Spontaneous baryogenesis at the weak phase transition

Year: 1991

Type: article

Abstract: We discuss baryogenesis during the weak phase transition in models with CP violation in the scalar potential. If the transition is first order, classical evolution of the scalar fields can split particle-antiparticle energy levels. A net baryon number will then be produced by anomalous weak baryon number violation. We can explain the observed value ϱBS≅10−10.
