dc.description.abstract | We report on measurements of a charge-dependent flow using a novel three-particle correlator with ALICE in
Pb-Pb collisions at the CERN Large Hadron Collider (LHC), and discuss the implications for observation of local
parity violation and the chiral magnetic wave (CMW) in heavy-ion collisions. Charge-dependent flow is reported
for different collision centralities as a function of the event charge asymmetry. While our results are in qualitative
agreement with expectations based on the CMW, the nonzero signal observed in higher harmonics correlations
indicates a possible significant background contribution. We also present results on a differential correlator, where
the flow of positive and negative charges is reported as a function of the mean charge of the particles and their
pseudorapidity separation. We argue that this differential correlator is better suited to distinguish the differences
in positive and negative charges expected due to the CMW and the background effects, such as local charge
conservation coupled with strong radial and anisotropic flow. | en |
