Mixed harmonic azimuthal correlations in Pb--Pb collisions at \sqrt{s_{NN}}=2.76TeV measured with the ALICE experiment at the LHC

Abstract

Mixed harmonic charge dependent azimuthal correlations at mid-rapidity in Pb-Pb collisions at \sqrt{s_{NN}} = 2.76 TeV were measured with the ALICE detector at the LHC. A clear charge dependence for a series of correlations is observed both via the multi-particle cumulant and the event plane methods. Implications from these measurements for the possible effects of local parity violation in QCD and for models which incorporate azimuthal anisotropic flow and "effective" local charge conservation on the kinetic freeze-out surface are discussed.Comment: 6 pages, 5 figures, proceedings of International symposium on multiparticle dynamics 2012 (ISMD2012
