Single slepton production in association with a single top quark at the Fermilab Tevatron and CERN LHC

We calculate the total cross section for single charged slepton production in association with a top quark at hadron colliders in the baryon-triality (B-3) supersymmetric model. We compute event rates for the Fermilab Tevatron and CERN LHC. We study the signatures for different supersymmetric scenarios including neutralino and stau lightest supersymmetric particles. We perform a detailed analysis with basic cuts for the B-3 operator lambda(231)' using Monte Carlo simulations to show that the signal can be distinguished from the background at the LHC. In particular, we employ the resulting lepton charge asymmetry.
