Higgs production plus two jets at hadron colliders

TL;DR

This paper calculates Higgs production with two jets at hadron colliders, analyzing the full top-quark mass dependence and comparing it to the large top-mass approximation, with implications for distinguishing production mechanisms.

Contribution

It provides a detailed calculation including full top-quark mass effects and compares different Higgs production processes and their observable distributions.

Findings

Large top-mass limit is valid for certain Higgs and jet energy ranges.

Differences in rapidity and azimuthal distributions can distinguish production mechanisms.

Full mass dependence improves accuracy of Higgs plus two jets predictions.

Abstract

In this talk we present a calculation of Higgs production via gluon fusion in association with two jets, including the full top-quark mass dependence, and compare it to the large top-mass limit. We find that the large top-mass limit is a good approximation as long as the Higgs mass is smaller than the top quark pair mass, and the jet transverse energies are smaller than the top mass. In addition, we compare Higgs production via gluon fusion and via weak-boson fusion, and consider final-state distributions, like the rapidity interval between the jets and the jet-jet azimuthal decorrelation, which may allow us to distinguish one fusion process from the other.
