DESCRIPTION:Speakers: Ante Bilandzic (Technische Universitaet Muenchen (DE
 ))\nMultiparticle azimuthal correlations are utilized in anisotropic flow 
 stud- ies as observables sensitive to the properties of Quark-Gluon Plasma
  (QGP)\, an extreme state of matter which can be produced in ultra-relativ
 istic heavy- ion collisions. We will present the first results [1] for ell
 iptic (v2)\, triangular (v3) and quadrangular flow (v4) of charged particl
 es in Pb–Pb collisions at √sNN = 5.02 TeV recorded by ALICE during the
  LHC Run 2 operations. The comparison of experimental measurements to vari
 ous theoretical calculations will be discussed.\nIn addition\, results are
  reported for so-called symmetric cumulants. De- veloped by ALICE\, these 
 new multiparticle observables depend only on the correlations between even
 t-by-event amplitude fluctuations of anisotropic flow harmonics vn\, and a
 re therefore independent on the corresponding sym- metry planes. The centr
 ality dependence of correlation between fluctuations of the elliptic\, v2\
 , and quadrangular\, v4\, flow harmonics\, as well as of anti- correlation
  between v2 and triangular\, v3\, flow harmonics will be discussed in two 
 different regimes for the initial stages: geometry-dominated (in mid- cent
 ral heavy-ion collisions) and fluctuation-dominated (in the most central h
 eavy-ion collisions).\nThe measurement of individual flow harmonics togeth
 er with symmetric cumulants further constrain details of initial stages an
 d the transport prop- erties of the produced QGP. These results offer a un
 ique opportunity to test the validity of the hydrodynamic picture and to d
 iscriminate between vari- ous possibilities for the temperature dependence
  of shear viscosity to entropy density ratio of the produced QGP.\n\nhttps
