Theoretical results for charged-Higgs production

TL;DR

This paper provides detailed theoretical calculations of charged-Higgs production processes, including higher-order QCD corrections, showing their significant impact on cross sections and distributions.

Contribution

It presents the first comprehensive aN$^3$LO calculations for charged-Higgs production in association with top quarks and W bosons, highlighting the importance of radiative corrections.

Findings

Higher-order corrections significantly affect cross sections.

Differential distributions are substantially modified by radiative effects.

Theoretical predictions are more precise with aN$^3$LO corrections.

Abstract

I discuss charged-Higgs production via two different processes: in association with a top quark, and in association with a $W$ boson. I present total cross sections and differential distributions that include higher-order corrections from soft and collinear gluon emission through aN$^3$LO. I show that these radiative corrections are significant.
