Title: Baryogenesis at Electroweak Scale and Electric Dipole Moments in MSSM

Abstract: New CP violation sources is available in MSSM, making electroweak
baryogenesis (EWB) possible. However, the CP violation needed in EWB is 
believed to be strongly constrained by non-observation of electric dipole 
moments (EDMs). Among all the contributions to EDMs, the chargino-neutralino
two-loop contribution is the most relevant part for EWB. Based on a full 
calculation of this contribution, we conclude that the bino-driven EWB 
scenario is the least constrained one from EDM experimental bounds.
