Spectator processes and baryogenesis

High Energy Physics - Phenomenology 2009-11-07 v1

Abstract

Spectator processes which are in thermal equilibrium during the period of baryogenesis influence the final baryon asymmetry. We study this effect quantitatively for thermal leptogenesis where we find a suppression by a factor O(1).
