Abstract

This study investigates Quark-Gluon Plasma (QGP) in heavy-ion collisions through two avenues: high-p_⊥ frameworks and hydrodynamic modeling. Using the T_RENTo model, we find that IP-Glasma mimicking p=0 value aligns well with high-p_⊥ data, in agreement with Bayesian analysis of the low-p_⊥ regime. While adjusting p values may improve a fit to a particular high-p_⊥ observable, it does not permit an earlier onset of transverse expansion.
