Higgs boson production in association with three jets via gluon fusion at the LHC: Gluonic contributions

TL;DR

This paper calculates Higgs boson production with three jets via gluon fusion at the LHC, including full quark mass effects beyond the effective theory, revealing significant deviations at high transverse momentum.

Contribution

It introduces a calculation that incorporates full top and bottom quark mass dependence at leading order for Higgs plus three jets via gluon fusion, surpassing the heavy top approximation.

Findings

Deviations up to 100% from effective theory at high pT.

Includes full mass dependence of top and bottom quarks.

Analyzes differential distributions for Higgs plus three jets.

Abstract

Higgs production in association with three jets via gluon fusion (GF) is an important channel for the measurement of the CP-properties of the Higgs particle at the LHC. In this letter, we go beyond the heavy top effective theory approximation and include at LO the full mass dependence of the top- and bottom-quark contributions. We consider the dominant sub-channel gg -> H ggg which involves the manipulation of massive rank-5 hexagon integrals. Furthermore, we present results for several differential distributions and show deviations from the effective theory as large as 100% at high pT for light Higgs masses.
