Single-top hadroproduction in association with a W boson

TL;DR

This paper calculates the Wt single-top production process at next-to-leading order in QCD, integrating it with parton showers to improve understanding of the Wtb vertex and distinguish it from top pair production.

Contribution

It introduces a next-to-leading order calculation of Wt single-top production interfaced with parton showers, enhancing analysis of the Wtb vertex.

Findings

Provides a detailed NLO calculation of Wt production

Offers methods to distinguish Wt from top pair production

Enhances understanding of the Wtb vertex

Abstract

We present the calculation of the Wt single-top production channel to next-to-leading order in QCD, interfaced with parton showers within the MC@NLO formalism. This channel provides a complementary way of investigating the properties of the Wtb vertex, with respect to the s- and t-channels. We pay special attention to the separation of this process from top quark pair production.
