Single top quark production via SUSY-QCD FCNC couplings at the CERN LHC in the unconstrained MSSM

We evaluate the $t\bar{c}$ and $t\bar{u}$ productions at the LHC within the general unconstrained MSSM framework. We find that these single top quark productions induced by SUSY-QCD FCNC couplings have remarkable cross sections for favorable parameter values allowing by current precise experiments, which can be as large as a few pb. Once large rate of the single top quark signals are detected at the LHC, it may be induced by SUSY FCNC couplings. We show that the precise measurement of single top quark production cross sections at the LHC is a powerful probe of the details of the SUSY FCNC couplings.
