We present a new determination of q̂, the jet transport coefficient of the quark-gluon plasma. Using the JETSCAPE framework, we use Bayesian parameter estimation to constrain the dependence of q̂ on the jet energy, virtuality, and medium temperature from experimental measurements of inclusive hadron suppression in Au-Au collisions at RHIC and Pb-Pb collisions at the LHC. These results are based on a multi-stage theoretical approach to in-medium jet evolution with the MATTER and LBT jet…

Energy versus centrality dependence of the jet quenching parameter $$\hat{q}$$q^ at RHIC and LHC: a new puzzle?

TLDR
The central goal of jet quenching studies in high-energy nuclear collisions is the characterization of those QCD medium properties that are accessible by these probes, and an extraction of this parameter using data of inclusive particle suppression at RHIC and LHC energies for different centralities is presented.
