Transport properties of the matter created in heavy-ion collisions, the quark-gluon plasma (QGP), contain essential information about quantum chromodynamics (QCD). In this talk, we present our latest study in inferring the transport properties of QGP by an improved Bayesian analysis using the CERN Large Hadron Collider Pb-Pb data. The uncertainties of the extracted properties are reduced by adding new observables sensitive to specific shear and bulk viscosity, reflecting mostly nonlinear hydrodynamic responses. The analysis also reveals that higher-order harmonic flows and their correlations have a higher sensitivity to the transport properties than other observables. This observation shows the necessity of accurate measurements of these observables including heavy quarks in the future.

Jet quenching parameter in QCD kinetic theory
Boguslavski, K.; Kurkela, A.; Lappi, T.; Lindenbauer, F.; Peuron, J. (American Physical Society, 2024)We study the jet quenching parameter q^ in a non-equilibrium plasma using the QCD effective kinetic theory. We discuss subleading terms at large jet momentum p, show that our expression for q^ reproduces thermal results ... -
Success and challenges of flow harmonic analysis in LHC collisions from large to small systems
Kim, Dong Jo (2022)One of the primary goals of heavy-ion physics is to understand the transport properties of the quark-gluon-plasma (QGP) which comprises the tiniest constituents, quarks and gluons, that prevailed in the first few microseconds ...
