Probing Early-Time Dynamics and Quark-Gluon Plasma Transport Properties with Photons and Hadrons
Abstract
We use a hybrid model which relies on QCD effective kinetic theory -- K -- to dynamically bridge the gap between IP-Glasma initial states and viscous hydrodynamics, for the theoretical interpretation of heavy-ion collision results. The hydrodynamic phase is then followed by dynamical freeze-out handled by UrQMD. It is observed that the new pre-equilibrium/pre-hydro phase does influence the extraction of transport coefficients. We also show how the early dynamics is reflected in photon observables.
