Description

The relativistic hydrodynamic model has been vital to the analysis of the QCD matter created in high-energy heavy-ion collisions. Experimental data indicate that low momentum particles are thermal and hydrodynamic, while high momentum particles are non-thermal and perturbative. In this study, we investigate two scenarios - (i) the 'violet' hydrodynamic model where an extended momentum range is treated as hydrodynamic based on nonextensive statistics, and (ii) the 'red' hydrodynamic model where high momentum contributions are excluded from the bulk medium - to elucidate the momentum dependence of thermalization/hydrodynamization and its effect on flow observables in heavy-ion collisions using numerical simulations.
