Supersymmetric QCD Corrections to Single Top Quark Production at the Fermilab Tevatron

Abstract

We evaluate the supersymmetric QCD corrections to single top quark production via $q{\bar{q}}^{\prime }\to t\bar{b}$ at the Fermilab Tevatron in the minimal supersymmetric model. We find that within the allowed range of squark and gluino masses the supersymmetric QCD corrections can enhance the cross section by a few percent. The combined effects of SUSY QCD, SUSY EW, and the Yukawa couplings can exceed 10% for the smallest allowed $\tan \beta (\simeq 0.25)$ but are only a few percent for $\tan \beta >1$.
