Systematic Extraction of QGP Properties

Abstract

We investigate the collision energy dependence of shear viscosity over the entropy density ratio $\eta /s$ in Au+Au collisions at $\sqrt{s_{NN}}=19.6,39$, and $62.4$ GeV, using Bayesian statistical analysis and Gaussian process emulators to explore the full input parameter space of a transport+hydrodynamics hybrid model. The ratio is found to decrease as a function of collision energy, supporting the results from previous studies performed with the same hybrid model.
