摘要：We discuss the production of single top-quark final states by direct supersymmetric flavorchanging
interactions at the LHC. The total cross section s (pp(gg) → tc +tc) is computed at
the 1-loop order within the unconstrained MSSM. We prove that SUSY-QCD effects may furnish
sizeable production rates amounting up to ∼ 105 tc(ct) events per 100fb-1 of integrated luminosity,
in full compliance with the stringent low-energy constraints from b → sg . Furthermore,
we show that the cooperative SUSY-EW effects can be sizeable on their own, regardless of the
SUSY-QCD contribution, with maximum production rates of the order of 103 events per 100fb-1.
Owing to the fact that FCNC production of electrically neutral heavy-quark pairs is virtually absent
within the SM, we conclude that the observation of such pp(gg)→tc +tc processes at the
LHC could lead to evidence of new physics – of likely supersymmetric nature.
