Abstract

Measurements of charge dependent azimuthal correlations with the ALICE detector at the LHC are reported for Pb–Pb collisions at √sNN = 2.76 TeV. Two– and three–particle charge–dependent az- imuthal correlations in the pseudo–rapidity range |η| < 0.8 are presented as a function of the collision centrality, particle separation in pseudo–rapidity, and transverse momentum. A clear signal compati- ble with a charge–dependent separation relative to the reaction plane is observed, which shows little or no collision energy dependence when compared to measurements at RHIC energies. This provides a new insight for understanding the nature of the charge dependent azimuthal correlations observed at RHIC and LHC energies.
