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

We calculate the O(αewMₜ²/MW²) supersymmetric (SUSY) electroweak corrections to single top quark production via qq̄^'→tb̄ 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 {β} > 1, but can exceed 10% for tan {β} 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.
