TL;DR

This paper investigates gluon saturation effects in dijet production during p-Pb collisions at the LHC, revealing significant suppression of jet decorrelations due to gluon density saturation in nuclei.

Contribution

It provides the first detailed analysis of saturation effects in dijet production in p-Pb collisions using high energy factorization.

Findings

Significant suppression of jet decorrelations in p-Pb compared to p-p

Evidence of gluon density saturation in nuclei at low momentum fractions

Probing gluon saturation effects with central-forward jet configurations

Abstract

We study saturation effects in the production of dijets in p-p and p-Pb collisions using the framework of high energy factorization. We focus on central-forward jet configurations, which allow for probing gluon density at low longitudinal momentum fraction. We find significant suppression of the central-forward jet decorrelations in p-Pb compared to p-p, which we attribute to saturation of gluon density in nuclei.
