Measurement of event-by-event flow harmonics in Pb-Pb Collisions at sNN=2.76TeV with the ATLAS detector

The event-by-event distributions of harmonic flow coefficients vn for n=2 - 4 are measured in Pb-Pb collisions at sNN=2.76TeV, using charged particles with pT>0.5GeV and |η|<2.5. The shape of the vn distributions is consistent with Gaussian fluctuations in central collisions for v2 and over the measured centrality range for v3 and v4. When these distributions are rescaled to the same 〈vn〉, the resulting shapes are similar for pT>1GeV and 0.5
