Jet quenching and effects of non-Gaussian transverse-momentum broadening on di-jet observables

TL;DR

This paper investigates how non-Gaussian transverse-momentum broadening affects di-jet observables in ultrarelativistic nuclear collisions, combining high energy factorization with in-medium jet propagation models.

Contribution

It introduces a qualitative framework that incorporates stochastic transverse forces and medium-induced radiation to study non-Gaussian effects on jet pairs.

Findings

Di-jet observables deviate from Gaussian broadening predictions.

Non-Gaussian effects significantly influence di-jet correlations.

The framework highlights the importance of stochastic transverse forces.

Abstract

We study, at a qualitative level, production of jet pairs in ultrarelativistic nuclear collisions within a framework combining High Energy Factorisation (HEF) and in-medium propagation of jet particles that takes into account stochastic transverse forces as well as medium-induced radiation. We find that the resulting di-jet observables feature the behaviour deviating from that of jet-pairs which undergo transverse-momentum broadening following the Gaussian distribution.
