N2 - Charge-dependent anisotropy Fourier coefficients (νn) of particle azimuthal distributions are measured in pPb and PbPb collisions at √SNN = 5.02 TeV with the CMS detector at the LHC. The normalized difference in the second-order anisotropy coefficients (ν2) 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 ν3 shows a similar linear dependence with the same slope as seen for ν2. The observed similarities between the ν2 slopes for pPb and PbPb, as well as the similar slopes for ν2 and ν3 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 ν2 in heavy ion collisions arises from a chiral magnetic wave.
