# Parton energy loss in the reformulated weakly-coupled kinetic approach

## TL;DR

This paper develops a numerical approach to model parton energy loss in quark-gluon plasma by combining soft and hard interactions, analyzing how the cutoff affects parton distributions.

## Contribution

It introduces a systematic numerical implementation that separates soft and hard parton-plasma interactions within a kinetic framework.

## Key findings

- Dependence of parton distribution on soft-hard cutoff analyzed
- Soft interactions modeled via stochastic approach with transport coefficients
- Results applicable to phenomenological strong coupling scenarios

## Abstract

Interactions between hard partons and the quark-gluon plasma range from frequent soft interactions to rare hard scatterings. The larger number of soft interactions makes possible an effective stochastic description of parton-plasma interactions in terms of drag and diffusion transport coefficients. In this work, we present a numerical implementation that builds upon this systematic division between soft and hard parton-plasma interactions. We study the dependence of the single parton distribution on the cutoff between soft and hard parton-plasma interactions, both for small and phenomenological values of the strong coupling constant.
