Abstract

The flavor-changing top-quark decay t→ c h, where h is the lightest CP-even Higgs boson in the minimal supersymmetric standard model, is examined in the R-parity-violating supersymmetric model. Within the existing bounds on the relevant R-parity-violating couplings, the branching fraction for t→ c h can be as large as about 10^-5 in some part of the parameter space.
