Charge separation measurements in Pb–Pb collisions at LHC energies

The prospect of observing parity violation from the strong interaction in relativistic heavy–ion collisions has recently gained great attention. We present the measurements of the azimuthal asymmetry of charged hadron production in Pb–Pb collisions at = 2.76 TeV via the study of a parity even 3- and 2-particle azimuthal correlator. The results for LHC energies are compared to the ones reported by RHIC experiments but also to different models and to predictions from theory. The possible implications of these measurements to the local parity violation and the contribution from background effects are discussed.
