Abstract :
We propose a simple scenario for baryogenesis in supersymmetric models where baryon number is broken alongwith R-parity. The lightest supersymmetric particle (neutralino) decays to three quarks and CP-violation comes from interference of tree and one loop box diagrams. The bounds on the R-parity breaking couplings from the out-of-equilibrium condition are considerably relaxed in this scenario.
