Description
The long-range azimuthal correlations in the nucleus-nucleus collisions are one of the signals of creation of the Quark-Gluon Plasma. At the LHC energies similar correlations are observed also in p+Pb and even pp collisions. After several years of successful operation of the Large Hadron Collider a wealth of data on pp, p+Pb and Pb+Pb collisions is available. This makes possible detailed studies of different aspects of the azimuthal correlations. The ATLAS experiment studied extensively the subevent cumulant methods which allow to remove non-flow correlations, especially in the events with low multiplicity like those in pp and p+Pb collisions. Most recently the elliptic flow in Z-boson tagged pp collisions was also measured.
