%X The dominant contribution to the theoretical uncertainty in the extracted weak parameters of the Standard Model comes from the hadronic uncertainties in the electroweak boxes, i.e. γ−W<sup>±</sup>/Z exchange diagrams. A dispersive analysis relates the box diagrams to the parity-odd structure function, F<sub>3</sub>, for which the experimental data either do not exist or belong to a separate isospin channel. Therefore a first-principles calculation of F<sub>3</sub> is highly desirable. In this contribution, we report on the QCDSF/UKQCD Collaboration's progress in calculating the moments of the F<sub>3</sub><sup>γZ</sup> structure function from the forward Compton amplitude at the SU(3) symmetric point.
