Content

Modern advances in experimental techniques now make it possible to test the weak interaction in nucleon/nuclear systems. In order to reliably interpret such measurements as tests of the standard model, it is often a necessity to make the assumption of good charge symmetry underlying the hadronic/nuclear interactions. Recent lattice QCD simulations have started to constrain the charge symmetry breaking effects in nucleon form factors and parton distribution functions, however for a full description, effects from the differences in the up and down quark charges must also be taken into account.

In this talk we present results from a preliminary study of nucleon matrix elements calculated on the QCDSF QCD+QED configurations. In particular, the results presented here represent the first steps to revealing the electromagnetic contribution to CSV in nucleon form factors.
