Measurement of the centrality and pseudorapidity dependence of the integrated elliptic flow in lead–lead collisions at √s<sub>NN</sub> = 2.76 TeV with the ATLAS detector

The integrated elliptic flow of charged particles produced in Pb+Pb collisions at √s<sub>NN</sub> = 2.76 TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, v<sub>2</sub>, was measured in the pseudorapidit...

description The integrated elliptic flow of charged particles produced in Pb+Pb collisions at √s<sub>NN</sub> = 2.76 TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, v<sub>2</sub>, was measured in the pseudorapidity range |η| ≤ 2.5 with the event-plane method. In order to include tracks with very low transverse momentum p<sub>T</sub>, thus reducing the uncertainty in v<sub>2</sub> integrated over p<sub>T</sub>, a 1 μb<sub>−1</sub> data sample recorded without a magnetic field in the tracking detectors is used. The centrality dependence of the integrated v<sub>2</sub> is compared to other measurements obtained with higher p<sub>T</sub> thresholds. The integrated elliptic flow is weakly decreasing with |η|. The integrated v<sub>2</sub> transformed to the rest frame of one of the colliding nuclei is compared to the lower-energy RHIC data.
