Bounds on R-parity violating SUSY Yukawa couplings from semileptonic decays of baryons

Abstract

We consider tree-level corrections to hypercharge changing semileptonic decays of certain baryons induced by a minimal supersymmetric standard model with explicitly broken R-parity via $L$-violation. This study leads to a new set of constraints on the products of couplings arising from the LQd${}^c$ operator of the superpotential.
