Constraints on R parity and B violating couplings in gauge-mediated supersymmetry breaking models

We consider the proton decay involving a light gravitino or axino in gauge-mediated supersymmetry breaking models to derive constraints on the R parity and baryon number violating Yukawa couplings. Bounds on all nine coupling constants are obtained by considering the decay amplitudes at one-loop order. (C) 1998 Elsevier Science B.V. All rights reserved.
