Supersymmetric QCD corrections to single top quark production at hadron colliders

We present the calculations of the supersymmetric QCD corrections to the total cross sections for single top production at the Fermilab Tevatron and the CERN Large Hadron Collider in the minimal supersymmetric standard model. Our results show that, for the s-channel and t-channel, the supersymmetric QCD corrections are at most about 1%, but for the associated production process pp -> tW, the supersymmetric QCD corrections increase the total cross sections significantly, which can reach about 6% for most values of the parameters. Thus, the supersymmetric QCD corrections should be taken into consideration in future high precision experimental analyses for top physics.
