Three-loop soft anomalous dimensions for top-quark production

High Energy Physics - Phenomenology 2023-02-21 v1

Abstract

I present results through three loops for soft anomalous dimensions that control soft-gluon emission in processes involving the top quark. In particular I present results for channels in single-top production and top-pair production as well as for processes with new physics, including tZtZ, tZtZ', tγt \gamma, and tHtH^- production. These calculations are ingredients to resummations at N3^3LL accuracy and to derivations of N3^3LO soft-gluon corrections.
