The measurement of elliptic flow and higher-order flow harmonics of charged particles in sqrt{s_{NN}}=2.76 TeV Pb+Pb collisions with the ATLAS detector is presented. Fourier harmonics $v_{2}$ - $v_{6}$ were extracted with the event plane and two-particle correlation methods in a broad range of trans...

description The measurement of elliptic flow and higher-order flow harmonics of charged particles in sqrt{s_{NN}}=2.76 TeV Pb+Pb collisions with the ATLAS detector is presented. Fourier harmonics $v_{2}$ - $v_{6}$ were extracted with the event plane and two-particle correlation methods in a broad range of transverse momentum (0.5 GeV < p_{T} < 20 GeV), pseudorapidity (|\eta|<2.5) and collision centrality (0-80\%). Elliptic flow shows rapid rise with p_{T} up to about 3 GeV followed by a decrease within range 3-8 GeV and then becomes weakly dependent at the highest p_{T}. Similar trend is observed for higher-order harmonics. As a function of pseudorapidity a very weak dependence of all flow harmonics is measured. Results obtained with the two methods were found to be consistent.
