Charge-dependent anisotropy Fourier coefficients (vn) 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 (v2) between positively and negatively charge...

| description | Charge-dependent anisotropy Fourier coefficients (vn) 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 (v2) 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 v3 shows a similar
linear dependence with the same slope as seen for v2. The observed similarities between the v2 slopes for pPb and
PbPb, as well as the similar slopes for v2 and v3 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 v2 in heavy ion collisions arises from a chiral magnetic wave |
