Electroweak Corrections to t-channel single top production at the LHC

TL;DR

This paper calculates electroweak and SUSY one-loop corrections to t-channel single top production at the LHC, showing these effects are generally small and mainly influence the CKM Wtb coupling measurements.

Contribution

It provides the first detailed computation of $ ext{O}( ext{α}^3)$ electroweak corrections and SUSY contributions for single top production at hadron colliders.

Findings

Electroweak corrections are generally modest in the mSUGRA scenario.

SUSY contributions to these processes are small.

Experimental observables mainly depend on the CKM Wtb coupling.

Abstract

We describe the computation of the $\mathcal{O}(\alpha^3)$ corrections for single top (and single anti-top) production in the $t$-channel at hadron colliders. We show also The genuine one loop SUSY contribution to these processes. Such contributions are generally quite modest in the mSUGRA scenario. The experimental observables would therefore only practically depend, in this framework, on the CKM $Wtb$ coupling.
