TL;DR

This paper analyzes single and double inclusive forward jet production at the LHC using high energy factorization, comparing results with Pythia, and highlights the importance of including final state radiation effects.

Contribution

It provides a detailed description of forward jet spectra at 7 and 13 TeV using HEF and explores double parton scattering contributions, comparing with Monte Carlo simulations.

Findings

HEF effectively describes forward jet spectra

Double parton scattering influences azimuthal distributions

Comparison with Pythia shows HEF acts like an initial state shower

Abstract

We provide a description of the transverse momentum spectrum of single inclusive forward jets produced at the LHC, at the center-of-mass energies of 7 and 13 TeV, using the high energy factorization (HEF) framework. We subsequently study double inclusive forward jet production and, in particular, we calculate contributions to azimuthal angle distributions coming from double parton scattering. We also compare our results for double inclusive jet production to those obtained with the Pythia Monte Carlo generator. This comparison confirms that the HEF resummation acts like an initial state parton shower. It also points towards the need to include final state radiation effects in the HEF formalism.
