Measurements of Elliptic Flow with the ATLAS Detector

The measurement of the azimuthal anisotropy of charged particles obtained with the multi-particle correlations method is presented and compared to the results obtained with the event plane method for Pb + Pb collisions at 2.76 TeV from the ATLAS experiment. Results on flow harmonics, determined from the cumulants of particle correlations, over wide transverse momenta (0.5
