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

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 LQdc operator of the superpotential.
