Abstract
This thesis serves to summarize the recently developed microcanonical particlization pre-scription in heavy ion collisions, and study its effects on correlation observables in charged hadrons. As per the microcanonical ensemble, we partition the (3+1)D hypersurface into many so-called patch regions; where each patch is treated as an isolated system with con- served local charge quantities in (Q,B,S). I simulate sampling particles from the hypersurface and propagating them through the hadronic transport phase. By comparing to a baseline limit from grand canonical particlization, I study the enhancement of correlation strength due to microcanonical particlization. I systematically study the correlation strength over a range of rapidity ∆y and azimuthal angle separation ∆ϕ, between different pairs of hadrons: pions, kaons, and protons. The patch energy Epatch is indicative of the correlation strength, and I capture this trend in the width of the correlation functions. The study is performed at two collision energies √sNN = 200 GeV and √sNN = 19.6 GeV. I study the correlations in head-on collisions and peripheral collisions, and quantify flow-related effects in addition to effects on correlation strength.
