Query: Quark-hadron duality constraints on \gamma Z box corrections to
  parity-violating elastic scattering   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, and the approximate isospin independence of duality in the
electromagnetic nucleon structure functions down to Q^2 \approx 1 GeV^2.
Assuming that a similar behavior also holds for the \gamma Z proton structure
functions, we find that duality constrains the \gamma Z box correction to the
proton's weak charge to be \Re e\, \square_{\gamma Z}^V = (5.4 \pm 0.4) \times
10^{-3} at the kinematics of the Q_{\text{weak}} experiment. Within the same
model we also provide estimates of the \gamma Z corrections for future
parity-violating experiments, such as MOLLER at Jefferson Lab and MESA at
Mainz.
