A New Framework for Multijet Predictions and its application to Higgs Boson production at the LHC

TL;DR

This paper introduces a novel resummation-based framework for multi-jet observables, enabling accurate predictions for Higgs boson production with jets at the LHC by leveraging amplitude factorisation and analytic constraints.

Contribution

The paper develops a new theoretical framework for multi-jet calculations that improves upon existing methods by incorporating amplitude factorisation and analytic behaviour constraints.

Findings

Good agreement with known lowest order perturbative results

Predictions extend to all orders in the perturbative series

Application to Higgs production with jets at the LHC demonstrates framework's effectiveness

Abstract

We present a new framework for calculating multi-jet observables through resummation. The framework is based on the factorisation of scattering amplitudes in an asymptotic limit. By imposing simple constraints on the analytic behaviour of the result when applied away from this limit, we get good agreement with the known lowest order perturbative behaviour of the scattering amplitude, and predictions for the behaviour to all orders in the perturbative series. As an example of application we study predictions for Higgs Boson production through gluon fusion at the LHC in association with at least two jets.
