Tomography of a quark gluon plasma at RHIC and LHC energies

TL;DR

This paper models heavy quark interactions in quark-gluon plasma using perturbative QCD, predicting correlations and extending to LHC energies, and compares results with alternative approaches like AdS/CFT.

Contribution

It introduces a pQCD-based model for heavy quark energy loss that incorporates a running coupling and extends predictions to LHC energies, comparing with other theoretical frameworks.

Findings

Predicted correlations between charm quark pairs.

Provided methods to select central collisions experimentally.

Extended model predictions to LHC energy domain.

Abstract

Using the recently published model for the collisional energy loss of heavy quarks (Q) in a Quark Gluon Plasma (QGP), based on perturbative QCD (pQCD) with a running coupling constant, we study the interaction between heavy quarks and plasma particles in detail. We discuss correlations between the simultaneously produced $c$ and $\bar{c}$ quarks, study how central collisions can be experimentally selected, predict observable correlations and extend our model to the energy domain of the large hadron collider (LHC). We finally compare the predictions of our model with that of other approaches like AdS/CFT.
