- A light stop and electroweak baryogenesisPublication . Delepine, D.; Gerard, J. M.; Felipe, Ricardo Gonzalez; Weyers, J.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 upsilon(T-c)/T-c greater than or similar to 1 for baryogenesis can be satisfied in a range of the parameters of the model, consistent with present experimental bounds.
