Characterizations of the medium in jet quenching calculations

TL;DR

This paper compares four perturbative QCD-based formalisms for jet quenching in dense matter, analyzing their assumptions about medium structure and differences in physical processes to understand their implications.

Contribution

It provides a detailed comparison of existing jet quenching formalisms, focusing on their medium structure assumptions and physical process differences.

Findings

Different formalisms make distinct approximations about the medium

Major differences exist in the physical processes modeled

Comparison clarifies the implications of various assumptions

Abstract

The modification of hard jets in dense matter has so far been described by four different formalisms based on perturbative QCD (pQCD). In these proceedings, we compare the various approximations made in these different schemes, especially those regarding the structure of the medium through which jets propagate. Following this, we highlight some of the major differences in the various physical processes contained in the different approaches.
