Observation of charge-dependent azimuthal correlations in p-Pb collisions and its implication for the search for the chiral magnetic effect
Charge-dependent azimuthal particle correlations with respect to the second-order event plane in p-Pb and PbPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV have been studied with the CMS experiment at the LHC. The measurement is performed with a three-particle correlation tech...

| description | Charge-dependent azimuthal particle correlations with respect to the second-order event plane in p-Pb
and PbPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV have been studied with the
CMS experiment at the LHC. The measurement is performed with a three-particle correlation technique,
using two particles with the same or opposite charge within the pseudorapidity range jηj < 2.4, and a third
particle measured in the hadron forward calorimeters (4.4 < jηj < 5). The observed differences between
the same and opposite sign correlations, as functions of multiplicity and η gap between the two charged
particles, are of similar magnitude in p-Pb and PbPb collisions at the same multiplicities. These results pose
a challenge for the interpretation of charge-dependent azimuthal correlations in heavy ion collisions in
terms of the chiral magnetic effect. |
