Constraints on R parity and B violating couplings in gauge-mediated supersymmetry breaking models
arXiv:hep-ph/9802323 · doi:10.1016/S0370-2693(98)00371-2
Abstract
We consider the proton decay involving a light gravitino or axino in gauge-mediated supersymmetry breaking models to derive constraints on the parity and baryon number violating Yukawa couplings. Bounds on all nine coupling constants are obtained by considering the decay amplitudes at one-loop order.
