Measurement of flow harmonics with multi-particle cumulants in Pb+Pb collisions at root(s_NN) = 2.76 TeV with the ATLAS detector

Original language description

ATLAS measurements of the azimuthal anisotropy in lead-lead collisions at SQUARE ROOTsNN = 2.76 TeV are shown using a dataset of approximately 7?bMINUS SIGN 1 collected at the LHC in 2010. The measurements are performed for charged particles with transversemomenta 0.5 < pT < 20 GeV and in the pseudorapidity range |?| < 2.5. The anisotropy is characterized by the Fourier coefficients, vn, of the charged-particle azimuthal angle distribution for n = 2-4. The Fourier coefficients are evaluated using multi-particle cumulants calculated with the generating function method. Results on the transverse momentum, pseudorapidity and centrality dependence of the vn coefficients are presented. The elliptic flow, v2, is obtained from the two-, four-, six- and eight-particle cumulants while higher-order coefficients, v3 and v4, are determined with two- and four-particle cumulants. Flow harmonics vn measured with four-particle cumulants are significantly reduced compared to the measurement involving t
