Measurements of the chiral magnetic effect in Pb–Pb collisions with ALICE

We present the measurement of the charge-dependent 3-particle azimuthal correlation for unidentified charged particles in Pb–Pb collisions at √sNN = 5.02 TeV in ALICE. The results are compared with corresponding results from Pb–Pb collisions at √sNN = 2.76 TeV. We observe no significant difference i...

Description
Summary:We present the measurement of the charge-dependent 3-particle azimuthal correlation for unidentified charged particles in Pb–Pb collisions at √sNN = 5.02 TeV in ALICE. The results are compared with corresponding results from Pb–Pb collisions at √sNN = 2.76 TeV. We observe no significant difference in the charge-sensitive 3-particle correlator (γ112) between the two collision energies. Charged-dependent mixed-harmonic correlator (γ132) is also presented and compared with the predictions from a blast-wave model incorporating local charge conservation.
