P-Odd Pion Azimuthal Charge Correlations at LHC    [PDF]

Yachao Qian, Ismail Zahed

We argue that the instanton induced P-odd contributions to the Sivers effects in polarized proton-proton scattering, may cause substantial charge-dependent azimuthal correlations for $\pi^{\pm}$ production in unpolarized proton-proton scattering at the LHC. We suggest that this mechanism may still be substantial in peripheral heavy ion collisions both at RHIC and LHC.
