Abstract
We examine the consequences of a model for baryogenesis during the weak phase transition. We assume that baryon number violation comes from anomalous weak interactions and that the necessary CP violation comes from neutrino masses. We find that a baryon to entropy ratio of 10 −10 can be produced if the weak phase transition is first order, the tau neutrino mass is ∼ 30 MeV, and anomalous weak baryon violation is sufficiently rapid.
