Electroweak Baryogenesis in a Left-Right Supersymmetric Model

Abstract

The possibility of electroweak baryogenesis is considered within the framework of a left-right supersymmetric model. It is shown that for a range of parameters the large sneutrino VEV required for parity breaking varies at the electroweak phase transition leading to a production of baryons. The resulting baryon to entropy ratio is approximated to be ${n_B\over s}\sim \alpha 0.7 \times10^{-8}$, where $\alpha$ is the angle that the phase of sneutrino VEV changes at the electroweak phase transition.
