Anisotropic flow measurements in Pb--Pb collisions at 5.02 TeV with ALICE

Abstract

Anisotropic flow is a sensitive probe of the initial conditions and the transport properties of the Quark Gluon Plasma (QGP) produced in heavy-ion collisions. In these proceedings, we present the first results of elliptic ($v_2$), triangular ($v_3$) and quadrangular flow ($v_4$) of charged particles in Pb--Pb collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=$ 5.02 TeV with the ALICE detector. In addition, the comparison of experimental measurements to various theoretical calculations will be discussed. This provides a unique opportunity to test the validity of the hydrodynamic picture and discriminates between various possibilities for the temperature dependence of shear viscosity to entropy density ratio of the produced QGP.
