On Electroweak Baryogenesis in Gauge Mediated Models with Messenger-Matter Mixing

Abstract

We consider feasibility of electroweak baryogenesis in gauge mediated supersymmetry breaking models with messenger-matter mixing. We present a class of models where electroweak baryogenesis produces sufficient amount of baryon asymmetry. The main features of these models are ( i) large mixing between messengers and right stop and ( ii) fairly narrow region of viable β.
