# Quark and Gluon Jet Energy Loss

## TL;DR

This paper investigates the energy loss differences between quark and gluon jets in a weakly-coupled medium using the JEWEL Monte-Carlo generator, revealing that their relative energy loss approaches a constant at high energies, contrary to simple expectations.

## Contribution

It provides a detailed simulation-based analysis of quark and gluon jet energy loss, showing their similar behavior and the approach to a constant relative loss at high energies.

## Key findings

- Relative energy loss approaches a constant at high jet energies.
- The constant value is significantly larger than the naive $C_F/C_A$ expectation.
- Quark and gluon jets lose energy similarly within the JEWEL framework.

## Abstract

We present a study of the relative energy loss of quark and gluon jets that traverse a weakly-coupled medium. The study is carried out with the jet quenching Monte-Carlo event generator JEWEL which has been validated for a large set of jet observables. We find that the relative energy loss of quark and gluon jets approaches a constant value at large jet energy and that value is significantly larger (closer to 1) than the single parton expectation of $C_F/C_A$. Within JEWEL quark and gluon jets lose energy similarly.
