Strong and electroweak supersymmetric corrections to single top processes at the Large Hadron Collider

Abstract

We present the one-loop corrections originating from QCD and electroweak interactions of supersymmetric origin within the minimal supersymmetric standard model to the single-top processes $bq\ensuremath{\rightarrow}t{q}^{\ensuremath{'}}$ and $q{\overline{q}}^{\ensuremath{'}}\ensuremath{\rightarrow}t\overline{b}$. We illustrate their impact on top quark observables accessible at the LHC in the ``$t+$jet'' final state, such as total cross section, several differential distributions, and left-right plus forward-backward asymmetries. We find that in many instances these effects can be observable for planned LHC energies and luminosities, quite large as well as rather sensitive to several minimal supersymmetric standard model parameters.
