Supersymmetric electroweak corrections to single top quark production at the Fermilab Tevatron

We calculate the O(alpha(cw)M(t)(2)/M-W(2)) supersymmetric (SUSY) electroweak corrections to single top quark production via <q(q)over bar>--><t(b)over bar> at the Fermilab Tevatron in the minimal supersymmetric model. The supersymmetric electroweak corrections to the cross section are at most a few percent for tan beta > 1, but 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.
