Description

Accurate theoretical predictions of jet suppression are necessary for studying the properties of QCD matter created in ultra-relativistic heavy ion collisions. However, testing the prediction accuracy - and extracting useful qualitative knowledge - is often limited by constraining the predictions to only few experimental probes at a time, and by using free parameters. To address this issue, we will present comprehensive suppression predictions, which run across all available probes and different centrality regions at RHIC and LHC. To generate these predictions, we use the finite size dynamical QCD formalism that we previously developed, together with its recent extensions to finite magnetic mass [1] and running coupling [2]; this formalism is integrated into a numerical procedure that uses no free parameters in model testing. We obtain a very good agreement with the experimental results across all particle species [2,3], for different centrality regions [4], and for both RHIC and LHC. We will also discuss improved qualitative understanding of the relevant experimental data, which follows from such comprehensive comparison. 1. M. Djordjevic and M.
