Electroweak phase transition and baryogenesis in the MSSM

Abstract

We have analyzed baryogenesis in the MSSM for the light stop scenario, where the phase transition is strong enough first order. We have found that enough baryon asymmetry can be generated provided that the phase of $\mu$ be $\simgt$ 0.01. Constraints from the electric dipole moment of the neutron enforce the first and second generation squarks to have masses O(few) TeV
