Jet-medium photons as a probe of parton dynamics

TL;DR

This paper investigates jet-medium photons as a tool to study quark dynamics in heavy ion collisions, comparing two models to understand their contribution to direct photon spectra.

Contribution

It introduces a comparative analysis of jet-medium photon spectra using MARTINI and CUJET energy loss models within the JETSCAPE framework.

Findings

Jet-medium photons significantly contribute to the intermediate pT direct photon spectrum.

The spectra differ between the MARTINI and CUJET models, indicating model sensitivity.

Jet-medium photons provide insights into the evolving quark distribution in heavy ion collisions.

Abstract

Photons resulting from jet-medium interactions offer the opportunity of studying the evolving quark distribution in a heavy ion collision. The spectra of jet-medium photons is presented within the JETSCAPE framework for two different energy loss models, MARTINI and CUJET. Jet-medium photons can contribute significantly to the spectrum of direct photons in the intermediate $p_T$ range.
