Collective flow effects on charge balance correlations and local   parity-violation observables in $\sqrt{s_{NN}}=2.76$ TeV Pb+Pb collisions at   the LHC
  We study the effects of collective flow on charge dependent azimuthal correlations at LHC energies. We propose a series of correlations as a signature of the combined effects of azimuthal collective flow and local charge conservation and perform an analysis within a statistical freeze-out model. We find that present LHC measurements of charge dependent azimuthal correlations are consistent with local charge conservation on the kinetic freeze-out surface. In view of experimental searches for signatures of the chiral-magnetic effect, we provide an alternative explanation of the charge dependence of the observed signal and propose additional measurements to disentangle the effects.
