Study of QGP with probes associated with photon at RHIC-PHENIX

TL;DR

This paper investigates the use of photon-associated probes in heavy-ion collisions at RHIC-PHENIX to study the properties of the quark-gluon plasma formed during the early collision phase.

Contribution

It presents new experimental results on photon-associated probes, enhancing understanding of the partonic matter in high-energy heavy-ion collisions.

Findings

Photon-associated probes effectively penetrate the dense matter.

Results provide insights into the early-stage quark-gluon plasma.

Data supports the use of photons as clean probes of the initial collision conditions.

Abstract

When heavy ions with high energy collide, a hot and dense matter is produced. As the matter expands, the matter undergoes cross-over phase transition from partonic matter to hadronic matter. Jets are created by high pT partons in the early phase of the collisions. Leptons and photons can penetrate the matter without strong interaction. For that reason, jets, leptons and photons are good probes to study the partonic matter in the early phase of the collisions. We report about two probes associated with photon and their results for PHENIX.
