摘要：

The measurement of elliptic flow and higher-order flow harmonics of charged particles in root 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 (vertical bar eta vertical bar < 2.5) and collision centrality (0-80%). Results obtained with the two methods were found to be consistent. 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.
