Title: γZ corrections to forward-angle parity-violating ep scattering

Abstract

We use dispersion relations to evaluate the γZ box contribution to parity-violating electron scattering in the forward limit, taking into account constraints from recent JLab data on electroproduction in the resonance region as well as high energy data from HERA. The correction to the asymmetry is found to be 1.2 +- 0.2% at the kinematics of the JLab Qweak experiment, which is well within the limits required to achieve a 4% measurement of the weak charge of the proton.
