Electroweak baryogenesis in a left-right supersymmetric model

The possibility of electroweak baryogenesis is considered within the framew ork of a left-right supersymmetric model. It is shown that for a range of p arameters the large sneutrino VEV required for parity breaking varies at th e electroweak phase transition leading to a production of baryons. The resu lting baryon to entropy ratio is approximated to be n(B)/s similar to alpha 0.7 x 10(-8), where alpha is the angle that the phase of sneutrino VEV cha nges at the electroweak phase transition.
