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

Abstract

We have calculated the $O({\alpha }_{ew}{M}_t^2/M_W^2)$ supersymmetric electroweak corrections to single top quark production via $q{\bar{q}}^{\prime }\to t\bar{b}$ at the Fermilab Tevatron in the minimal supersymmetric model. The supersymmetric electroweak corrections to the cross section are a few percent for $tan\beta >1$, and can exceed 10% for $tan\beta <1$. The combined effects of SUSY electroweak corrections and the Yukawa corrections can exceed 10% for favorable parameter values, which might be observable at a high-luminosity Tevatron.
