摘要In the minimal supersymmetric standard model the R-parity violating interactions can trigger various exotic three-body decays for the top quark, which may be accessible at the LHC. In this work we examine the R-violating decays t -> cX(1)X(2), which include the tree-level processes t -> cl(i)(-)l(j)(+) (l(i) = e, mu, tau) and t -> cd(i)(d) over bar (j) (d(i) = d, s, b), as well as the loop- induced processes t -> cgX (X = g, gamma, Z, h). We find that the hereto weakly constrained R-violating couplings can render the decay branching ratios quite sizable, some of which already reach the sensitivity of the Tevatron collider and can be explored at the LHC with better sensitivity.
