We discuss the production of single top-quark final states by directsupersymmetric flavor-changing interactions at the LHC. The total cross sectionpp(gg)->t\bar{c}+\bar{t}c is computed at the 1-loop order within theunconstrained MSSM. We prove that SUSY-QCD effects may furnish sizeableproduction rates amounting up to barely 10^5 t\bar{c}(c\bar{t}) events per 100fb^{-1} of integrated luminosity, in full compliance with the stringentlow-energy constraints from b->s gamma. Furthermore, we show that thecooperative SUSY-EW effects can be sizeable on their own, regardless of theSUSY-QCD contribution, with maximum production rates of the order of 10^3events per 100 fb^{-1}. Owing to the fact that FCNC production of electricallyneutral heavy-quark pairs is virtually absent within the SM, we conclude thatthe observation of such pp(gg)->t\bar{c}+\bar{t}c processes at the LHC couldlead to evidence of new physics - of likely supersymmetric nature.
