Higgs as a gluon trigger

TL;DR

This paper proposes using ratios of Higgs boson to Drell-Yan production to study gluon fusion processes at the LHC, aiming to mitigate pile-up effects in high-luminosity conditions.

Contribution

It introduces a novel approach to probe gluon fusion via ratio observables that are robust against pile-up, supported by Monte Carlo simulation results.

Findings

Ratios of Higgs to Drell-Yan production can be used to study gluon fusion.

Monte Carlo simulations support the feasibility of this method.

The approach is effective even in high pile-up conditions.

Abstract

In the forthcoming high-luminosity phase at the LHC many of the most interesting measurements for precision QCD studies are hampered by conditions of large pile-up, particularly at not very high transverse momenta. We study observables based on measuring ratios of color-singlet currents via Higgs boson and Drell-Yan production, which may be accessed also at large pile-up, and used for an experimental program on QCD physics of gluon fusion processes in the LHC high-luminosity runs. We present results of Monte Carlo calculations for a few specific examples.
