Flow correlation as a measure of phase transition

It is well known that at low temperature and baryon chemical potential the degrees of freedom of nuclear matter are color-neutral hadrons and at high temperature or at large baryon chemical potential matter is in the form of a quark-gluon plasma (QGP) in which the fundamental degrees of freedom are colored objects such as quarks and gluons. Nuclear matter at small baryon chemical potential (μB) and finite temperature (T) is believed to undergo a crossover transition from the hadronic phase to the QGP phase and a first order phase transition at relatively larger μ_B and the first order phase transition line terminates at a critical point. The present study aims to find a unique observable which connects QCD Equation of State (EoS) and the experimental data of heavy-ion collisions using hydrodynamical model
