CP-Violation and Baryogenesis in The Low Energy Minimal Supersymmetric Standard Model

Abstract

In the context of the minimal supersymmetric extension of the Standard Model the effect of a realistic wall profile is studied. It has been recently showed that in the presence of light stops the electroweak scale phase transition can be strong enough for baryogenesis. In the presence of non-trivial CP-violating phases of left-handed mixing terms and Higgsino mass, the largest $n_B/s$ is created when Higgsino and gaugino mass parameters are degenerate, $\mu =M_2$. In the present paper we show that realistic wall profiles suppress the generated baryon number of the universe, so that quite a stringent bound $|\sinϕ_μ| \gsim 0.2$ for $\mu$-phase ${\varphi }_{\mu }$ can be inferred.
