摘要：The flavor-changing top-quark decay t ! ch, where h is the lightest CPeven
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 ratio for t ! ch can be as large as about 10−5
in some part of the parameter space, reaching a level accessible at the LHC and at e+e−
Linear Colliders with high luminosities.
