  We argue that the large instanton induced Pauli form factor in polarized
proton-proton scattering may cause, through topological fluctuations,
substantial charge-dependent azimuthal correlations for pi^+/pi^- production in
peripheral heavy ion collisions both at RHIC and LHC, thanks to the large
induced magnetic field. Our results compare favorably to the measured pion
azimuthal correlations by the STAR and ALICE collaborations.
