Single Top Production in the Wt mode with MC@NLO

TL;DR

This paper investigates the feasibility of treating Wt production as a separate process at the LHC, using MC@NLO simulations to define and isolate the Wt mode despite interference with top pair production.

Contribution

The authors introduce two definitions of the Wt mode within MC@NLO and demonstrate their effectiveness in isolating Wt production at the LHC.

Findings

It is possible to distinguish Wt production from top pair production with appropriate cuts.

Two definitions of Wt mode quantify interference effects.

MC@NLO can reliably simulate Wt production as a separate process.

Abstract

We consider whether Wt production can be considered as a distinct production process at the LHC, separate from top pair production with which it interferes. We argue that this problem can be meaningfully addressed in an MC@NLO calculation, and give two definitions of the Wt mode whose difference measures the degree of interference between Wt and top pair production. These are then implemented in the MC@NLO software framework, and results given which demonstrate that it is indeed legitimate to isolate the Wt process, subject to adequate cuts.
