Abstract

We consider generation of baryon asymmetry of the universe through RR-parity violation in a scenario in which out-of-equilibrium condition is satisfied by making the electroweak phase transition to be first order. We study all the RR-parity violating interaction which can generate (BL)(B-L) asymmetry which then converts to baryon asymmetry of the universe. We demonstrate that CP--violating sfermion deudy all the RR-parity violating interaction which can generate (BL)(B-L) asymmetry which then converts to baryon asymmetry of the universe. We demonstrate that CP--violating sfermion decays contribute more than that of the neutralino decays in the generation of (BL)(B-L) asymmetry.
