Resolving the Higgs-Gluon Coupling with Jets

TL;DR

This paper analyzes the Higgs-gluon coupling via Higgs production with two jets, revealing logarithmic structures that can test the loop-induced nature of the coupling and improve signal detection.

Contribution

It derives the logarithmic structure of Higgs plus two jets production and demonstrates how the second jet enhances analysis sensitivity for testing the Higgs-gluon coupling.

Findings

Logarithmic structures in Higgs+2 jets production reveal top quark mass effects.

Second jet improves signal rate and background rejection in Higgs decay analyses.

Transverse momentum distributions exhibit key logarithmic behaviors.

Abstract

In the Standard Model the Higgs coupling to gluons is almost entirely induced by top quark loops. We derive the logarithmic structure of Higgs production in association with two jets. Just like in the one-jet case the transverse momentum distributions exhibit logarithms of the top quark mass and can be used to test the nature of the loop-induced Higgs coupling to gluons. Using Higgs decays to W bosons and to tau leptons we show how the corresponding analyses hugely benefit from the second jet in the relevant signal rate as well as in the background rejection.
