# Higher-order corrections to jet quenching

## TL;DR

This paper advances the understanding of jet quenching by calculating higher-order corrections that account for jet substructure fluctuations, revealing significant logarithmic effects requiring all-order resummation.

## Contribution

It introduces a method to include higher-order corrections in jet quenching calculations, moving beyond the single parton energy loss approximation.

## Key findings

- Higher-order corrections are significant in jet quenching.
- Large logarithmic contributions are identified and need resummation.
- Jet quenching is sensitive to jet substructure fluctuations.

## Abstract

We compute the inclusive jet spectrum in the presence of a dense QCD medium by going beyond the single parton energy loss approximation. We show that higher-order corrections are important yielding large logarithmic contributions that must be resummed to all orders. This reflects the fact that jet quenching is sensitive to fluctuations of the jet substructure.
