Event-by-event charge separation in Pb-Pb collisions at √s_NN = 2.76 TeV with ALICE

Kharzeev et al., proposed strong P and CP violation in heavy ion collisions. This is basically due to fact that in the non-central heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), the electric field induced by a strong magnetic field B ∼ 10¹⁵ T (eB ∼10⁴ MeV²), created by energetic spectator protons, causes charge separation along the system's angular momentum resulting the Chiral Magnetic Effect (CME). A Large Ion Collider Experiment (ALICE) is specifically designed to study the properties of Quark-Gluon Plasma (QGP), the deconfined state of quarks and gluons. The charge separation effect has been investigated by the STAR at different collision energies √s_NN = 7.7 - 200 GeV and by the ALICE at √s_NN= 2.76 TeV. The study of particle correlations is the only way to investigate charge separation due to the CME
