| Title | Quark-hadron duality constraints on $\gamma Z$ box corrections to parity-violating elastic scattering | ||||
| Abstract | We examine the interference $\gamma Z$ box corrections to parity-violating elastic electron-proton scattering in the light of the recent observation of quark-hadron duality in parity-violating deep-inelastic scattering from the deuteron at low $Q^2$. Using the similarity of electromagnetic and $\gamma Z$ structure function moments and those extracted from leading twist parton distributions down to $Q^2 \approx 1$~GeV$^2$, we find that duality constrains the $\gamma Z$ box correction to $\Re \square_{\gamma Z}^V = (5.4 \pm 0.4) \times 10^{-3}$ at the kinematics of the Q-weak experiment. Within the same model we also provide estimates of the $\gamma Z$ corrections for future experiments, such as MOLLER at Jefferson Lab and MESA at Mainz. | ||||
