$tW$ and $tZ'$ production at hadron colliders

TL;DR

This paper provides theoretical predictions for $tW$ and $tZ'$ production at hadron colliders, highlighting the dominance of soft-gluon corrections and analyzing cross sections and distributions at current and future collider energies.

Contribution

It offers the first detailed analysis of soft-gluon corrections for both Standard Model and new physics $tZ'$ production processes across a range of energies.

Findings

Soft-gluon corrections dominate the production processes.

Cross sections and distributions are computed for LHC and 100 TeV colliders.

Uncertainties from scale and PDF variations are quantified.

Abstract

We present theoretical results with soft-gluon corrections for two separate processes: (1) the production of a single top quark in association with a $W$ boson in the Standard Model; and (2) the production of a single top quark in association with a heavy $Z'$ boson in new physics models with or without anomalous couplings. We show that the higher-order corrections from soft-gluon emission are dominant for a wide range of collider energies. Results are shown for the total cross sections and top-quark transverse-momentum and rapidity distributions for $tW$ and $tZ'$ production at LHC and future collider energies up to 100 TeV. The uncertainties from scale dependence and parton distribution functions are also analyzed.
