Measurement of elliptic and higher order flow harmonics in 2.76 TeV Pb+Pb Collisions with the ATLAS detector

The flow harmonics $v_n$ are important bulk observables in heavy ion collisions. They contain information about the initial geometry as well as the transport properties of the medium produced in heavy ion collisions. We present the detailed measurements of flow harmonics $v_2$-$v_6$ using the EP met...

description The flow harmonics $v_n$ are important bulk observables in heavy ion collisions. They contain information about the initial geometry as well as the transport properties of the medium produced in heavy ion collisions. We present the detailed measurements of flow harmonics $v_2$-$v_6$ using the EP method and two particle correlations method in broad $p_T$, $eta$ and centrality ranges using the 2010 Pb+Pb data from ATLAS. The phase space regions where the two methods are consistent and where they disagree will be discussed. This result provides new insights on the origin of the long range ridge structures over broad $pT$ ranges (soft and hard ridges).
