A light stop and electroweak baryogenesis

The possibility of creating baryon asymmetry at the electroweak phase transition in the minimal supersymmetric standard model is considered for the case when right-handed squarks are much lighter than left-handed ones. It is shown that the usual requirement υ(T c) T c ≳ 1 for baryogenesis can be sat...

Description
Summary:The possibility of creating baryon asymmetry at the electroweak phase transition in the minimal supersymmetric standard model is considered for the case when right-handed squarks are much lighter than left-handed ones. It is shown that the usual requirement υ(T c) T c ≳ 1 for baryogenesis can be satisfied in a range of the parameters of the model, consistent with present experimental bounds.
