Abstract

We note that off the quark mass shell the operators (pi+pf)μγ5(p_i+p_f)_\mu\gamma_5 and iσμν(pipf)νγ5i\sigma_{\mu\nu}(p_i -p_f)^\nu\gamma_5, both of which reduce to σE-\vec{\sigma}\cdot\vec{E} in the non-relativistic limit, are no longer identical. In this paper we explore the effects of this difference in the contribution of these quark electric moments to hadronic electric moments.
