英文摘要: In the minimal supersymmetric model the R-parity violating top quark interactions, which are so far weakly constrained, can induce various flavor-changing neutral-current (FCNC) productions for the top quark at the large hadron collider (LHC). In this work we assume the presence of the B-violating couplings and examine their contributions to the FCNC productions proceeding through the parton processes cg -> t, gg -> t (c) over bar, cg -> t gamma, cg -> tZ and cg -> th. We find that all these processes can be greatly enhanced relative to the R-parity preserving predictions. In the parameter space allowed by current experiments, all the production channels except cg -> th can reach the 3 sigma sensitivity, in contrast to the R-parity preserving case in which only cg -> t can reach the 3 sigma sensitivity.
