Subject: Self-Correlations in fluctuation study of heavy ion collisions

Hydrodynamic modelling explains the behavior of quark gluon plasma in heavy ion collisions pretty well. Fluctuation in such hydrodynamic equations lets us study the various thermal and transport properties of the medium. Since critical points are characterized by large fluctuations, the hope is that this line of investigation will help us identify the presence of a critical point in the QCD phase diagram. In this talk I will describe the study of fluctuations in electric charge in heavy ion collisions using a causal noise called Catteneo noise. I will describe the numerical procedures involved in solving the Stochastic Differential Equations that appear in these simulations and I will describe a method to separate the physical two-point correlation from the so-called “self-correlations” that arise in any statistical system.
