Production of Higgs bosons with large transverse momentum

TL;DR

This paper presents the calculation of two-loop amplitudes for Higgs plus jet production at large transverse momentum, completing the NLO corrections crucial for accurate predictions in high-energy collider experiments.

Contribution

The paper introduces the first computation of two-loop amplitudes for key processes in Higgs plus jet production at high transverse momentum, filling a long-standing gap in NLO corrections.

Findings

Computed two-loop amplitudes for gg→Hg, qar{q}→Hg, qg→Hq processes.

Combined amplitudes with real corrections to produce NLO Higgs pT distribution.

Provides essential theoretical input for Higgs boson production analysis.

Abstract

Recent results on the Higgs plus jet production is reviewed. We have computed the two-loop amplitudes for $ gg \to Hg $, $ q\bar{q} \to Hg $ and $ qg \to Hq $ at the large Higgs transverse momentum. It was long-missing part of NLO corrections to the Higgs plus jet production above the top mass threshold. This results are combined with the real corrections to produce the Higgs boson transverse momentum distribution at NLO.
