TL;DR

This paper calculates the Higgs boson production rate at the LHC with high precision, focusing on next-to-leading order QCD corrections and gluon-initiated processes, using the infinite top mass approximation.

Contribution

It provides a detailed next-to-leading order QCD calculation of Higgs production rates, emphasizing the dominant gluon-initiated mechanism and validating the infinite top mass approximation.

Findings

Validation of the infinite top mass approximation in relevant kinematic domains.

Dominance of gluon-initiated processes in Higgs production cross section.

Abstract

In this work we seek to compute precisely the rate at which these Higgs particles are produced as a function of the transverse momentum and the rapidity at the Large Hadron Collider. This calculation is carried out to next leading order in the QCD strong coupling $\alpha_s$. In particular, this calculation includes the dominant gluon-initiated mechanism, which is responsible for the majority of the cross section. We work in the infinite top mass approximation, and argue that this is very precise in the domain of applicability.
