摘要：

We propose a simple scenario for baryogenesis in supersymmetric models where baryon number is broken alongwith ii-parity. The lightest supersymmetric particle (neutralino) decays to three quarks and CP-violation comes from interference of tree and one loop box dia,srams. The bounds on the R-parity breaking couplings from the out-of-equilibrium condition are considerably relaxed in this scenario. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
