Description

Transport properties of the matter created in heavy-ion collisions, the quark-gluon plasma, contain essential information about quantum chromodynamics (QCD). The Bayesian analysis has shown to be very effective in constraining the QCD matter properties [1], and the combined inclusion of LHC Pb--Pb 5.02 and 2.76 TeV data with additional flow observables has greatly narrowed down the uncertainties [1]. However, our latest studies show some shortages of the current modelling of the initial conditions and difficulties in describing RHIC Au--Au collision data. In this talk, we discuss our findings and new results to improve modelling of the initial conditions of heavy-ion collisions.
