Diffusion Enhances Spontaneous Electroweak Baryogenesis

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

We include the effects of diffusion in the electroweak spontaneous baryogenesis scenario and show that it can greatly enhance the resultant baryon density, by as much as a factor of 1/αw41061/\alpha_w^4 \sim 10^6 over previous estimates. Furthermore, the baryon density produced is rather insensitive to parameters characterizing the first order weak phase transition, such as the width and propagation velocity of the phase boundary.
