Single-top production in the Standard Model and beyond

TL;DR

This paper provides high-order theoretical calculations for single-top production processes in the Standard Model and beyond, including cross sections, distributions, and effects of anomalous couplings, with corrections up to NNNLO.

Contribution

It presents the first comprehensive high-order calculations for various single-top production channels, including effects of anomalous top-quark couplings.

Findings

NNNLO soft-gluon corrections significantly impact cross sections.

Distributions for top-quark transverse momentum and rapidity are provided.

Results include Standard Model and anomalous coupling scenarios.

Abstract

I present high-order calculations for single-top production in the Standard Model and in models with anomalous top-quark couplings. Theoretical results are presented for total cross sections and top-quark transverse momentum and rapidity distributions for the $t$ and $s$ single-top channels as well as for the associated production of a top quark with a $W$ boson in the Standard Model. Corrections from soft-gluon emission though NNNLO are included. I also show results for the associated production of a top quark with a $Z$ boson in processes involving anomalous top-quark couplings.
