Description

We study electroweak baryogenesis and electric dipole moments in the presence of the two leading-order, non-renormalizable operators in the Higgs sector of the MSSM (BMSSM). This simple extension has several differences over MSSM baryogenesis: (1) both stops can be light, allowing for stop-driven baryogenesis, (2) new CP-violating phases arise, and (3) baryogenesis can occur in much larger regions of parameter space. In particular, there is no fine-tuning in the stop sector. Nevertheless, electric dipole moments should be measured if experimental sensitivities are improved by about one order of magnitude.
