Hydrodynamics has been very successful in describing experimental data of relativistic nuclear collisions.
The hydrodynamic picture is now well established, enabling quantitative comparisons between hydrodynamic models and experimental data to extract the temperature dependence of the viscosities of the quark–gluon plasma.
Despite this great success, theoretical uncertainties in the initial conditions of hydrodynamic models remain largely unconstrained.
In this talk, I will highlight these issues in conventional hydrodynamic modeling by introducing two works focused on initial state modeling: the dynamical core–corona initialization model [1] and the (3+1)D MC-EKRT framework [2].
In the first part of my talk, I will talk about the cruciality of lacking non-equilibrium contribution in model-to-data comparisons in the conventional frameworks, while in the second part, I will introduce a new initial state Monte-Carlo event generator based on pQCD minijet production which accounts for the conservation of energy/momentum and valence-quark number.
