Abstract :
The flavor-changing top-quark decay t→ch, 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→ch can be as large as about 10−5 in some part of the parameter space.
