The normalized difference in the second-order anisotropy coefficients (v(2)) between positively and negatively charged particles is found to depend linearly on the observed event charge asymmetry with comparable slopes for both pPb and PbPb collisions over a wide range of charged particle multiplicity. In PbPb, the third-order anisotropy coefficient v(3) shows a similar linear dependence with the same slope as seen for v(2). The observed similarities between the v(2) slopes for pPb and PbPb, as well as the similar slopes for v(2) and v(3) in PbPb, are compatible with expectations based on local charge conservation in the decay of clusters or resonances, and constitute a challenge to the hypothesis that, at LHC energies, the observed charge asymmetry dependence of v(2) in heavy ion collisions arises from a chiral magnetic wave.eninfo:eu-repo/semantics/openAccessProbing the chiral magnetic wave in pPb and PbPb collisions at ?SNN=5.02 TeV using charge-dependent azimuthal anisotropiesArticle10.1103/PhysRevC.100.0649082-s2.0-850773954266Q1100WOS:000503237100004Q2
