Description
One of the key goals of the heavy-ion programs is to study the transport properties of the quark-gluon plasma (QGP) forming in the collisions of two nuclei, such as the specific shear viscosity η/s as a function of temperature T and baryon chemical potential μB. The precise extraction of such parameters may present a certain difficulties. To strengthen the constraints for η/s(T, μB) the modified Pearson correlation coefficient ρ(v22,[pT]) between the average transverse momentum [pT] and square of the elliptic flow coefficient v22 might be employed.
In this work, sensitivity of the correlation coefficient ρ(v22,[pT]) to the attenuation effects of the specific shear viscosity and the initial-state geometry of the collisions is studied using the UrQMD+vHLLE hybrid model to simulate Au+Au collisions. Measurements of the correlation between v22 and [pT] could aid precision extraction of η/s(T, μB) from the experimental data available at RHIC.
