Abstract
We have computed the complete one-loop electroweak effects in the MSSM for single top (and single antitop) production in the t-channel at hadron colliders, generalizing a previous analysis performed for the dominant dt final state and fylly including QED effects. The results are quite similar for all processes. The overall Standard Model one-loop effect is small, of the few percent size. This is due to a compenstion of weak and QED contributions that are of opposite sign. The genuine SUSY contribution is generally quite modest in the mSUGRA scenario. The experimental observables would therefore only practically depend, in this framework, on the CKM Wtb coupling.
