Single inclusive jet production and the nuclear modification ratio at very forward rapidity in proton-lead collisions with $\sqrt{s_{NN}}$ = 5.02 TeV

TL;DR

This paper predicts single inclusive jet spectra at very forward rapidity in proton-lead collisions at 5.02 TeV, exploring gluon saturation effects using Monte Carlo simulations within the High Energy Factorisation framework.

Contribution

It introduces a novel calculation of forward jet production in proton-lead collisions incorporating gluon saturation effects with Monte Carlo methods.

Findings

Gluon saturation leads to suppression of jet cross sections at forward rapidity.

Predictions show significant differences with and without saturation effects.

The approach combines KaTie and CASCADE Monte Carlo generators for comprehensive modeling.

Abstract

We present calculations of single inclusive jet transverse momentum and energy spectra at forward rapidity ($5.2\!<\!y\!<\!6.6$) in proton-lead collisions with $\sqrt{s_{NN}}$ = 5.02 TeV. The predictions are obtained with the KaTie Monte Carlo event generator, which allows to calculate interactions within the High Energy Factorisation framework. The tree-level matrix element results are subsequently interfaced with the CASCADE Monte Carlo event generator to account for hadronisation. The effects of the saturation of the gluon density, leading to suppression of the cross section, are investigated.
