BARYOGENESIS THROUGH R-PARITY VIOLATION

We consider the generation of the baryon asymmetry of the universe thr ough R-parity violation in a scenario in which the out-of-equilibrium condition is satisfied by making the electroweak phase transition firs t order. We study all the R-parity-violating interactions which can ge nerate (B-L) asymmetry which then converts to the baryon asymmetry of the universe. We demonstrate that CP-violating sfermion decays contrib ute more than that of the neutralino decays in the generation of (B-L) asymmetry.
