- Abstract
The ATLAS results on charged particles flow harmonics in Pb+Pb collisions at √sNN = 2.76 TeV are presented. Elliptic flow and higher order flow harmonics, vn (for n = 2-4), are measured using two methods: standard event plane and multi-particle cumulants (up to the 8th order). Results for elliptic flow are shown in a wide range of pseudorapidity (&#124η;| < 2.5), transverse momentum (0.5 < pT < 20 GeV) and centrality (0-80%). The measurement techniques are discussed in terms of non-flow effects. It is shown that four-particle correlations suppress most of non-flow contributions.
