Probing the shape of the quark-gluon plasma droplet via event-by-event quark-gluon plasma tomography

Abstract

This study investigates quark-gluon plasma in heavy-ion collisions through two avenues: high-p frameworks and hydrodynamic modeling. Using the TRENTo model, we find that the 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.
