Towards QCD-assisted hydrodynamics for heavy-ion collision phenomenology

Understand

Heavy-ion collisions are well described by a dynamical evolution with a long hydrodynamical phase.

• In this phase the properties of the strongly coupled quark-gluon plasma are reflected in the equation of state (EoS) and the transport coefficients, most prominently by the shear and bulk viscosity over entropy density ratios $\eta$/s(T) and $\zeta$/s(T), respectively.
• While the EoS is by now known to a high accuracy, the transport coefficients and in particular their temperature and density dependence are not well known from first-principle computations yet, as well as the possible influence they can have once used in hydrodynamical simulations.
• In this work, the most recent QCD-based parameters are provided as input to the MUSIC framework.
