Measurement of elliptic and higher-order flow harmonics at 2.76 TeV Pb-Pb collisions with the ATLAS detector

Anisotropy coefficients $v_n$ are important observables for studying the hot and dense medium created in heavy ion collisions. This paper presents a comprehensive measurement of the coefficients $v_2-v_6$, using the event plane method and two-particle correlation method, in the broad $p_T$, $\eta$ a...

description Anisotropy coefficients $v_n$ are important observables for studying the hot and dense medium created in heavy ion collisions. This paper presents a comprehensive measurement of the coefficients $v_2-v_6$, using the event plane method and two-particle correlation method, in the broad $p_T$, $\eta$ and centrality ranges using Pb-Pb data at $\sqrt{s_{NN}}=2.76$ TeV from the ATLAS experiment at the LHC. Both techniques lead to consistent results, $v_n$ rises at low $p_T$ then decreases in the range 3-8 GeV and become weakly dependent for the highest $p_T$ values. In contrast to measurements at RHIC energies $v_n$ are approximately independent of pseudorapidity.
