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

Abstract

We calculate the total cross section for single charged slepton production in association with a top quark at hadron colliders in the baryon-triality (${\mathrm{B}}_{3}$) 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 ${\mathrm{B}}_{3}$ operator ${\ensuremath{\lambda}}_{231}^{\ensuremath{'}}$ 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.
