Beam-energy dependence of the azimuthal anisotropic flow from RHIC

Abstract

Recent STAR measurements of the anisotropic flow coefficients (v${}_n$) are presented for Au+Au collisions spanning the beam energy range $\sqrt{s_{NN}}=7.7-200$ GeV. The measurements indicate dependences on the harmonic number ($n$), transverse momentum ($p_T$), pseudorapidity ($\eta$), collision centrality and beam energy ($\sqrt{s_{NN}}$) which could serve as important constraints to test different initial-state models and to aid precision extraction of the temperature dependence of the specific shear viscosity.
