Recently, it has been pointed out that there exists a connection between the generalized parton distribution E(x,0,t) and the Sivers effect for single-spin asymmetries. For transversely polarized nucleon targets, generalized parton distributions are asymmetric in impact parameter space. This impact parameter space asymmetry, together with the final state interaction of the active quark, gives rise to the Sivers effect in momentum space. We demonstrate this phenomenon explicitly in the scalar diquark model. This result also illustrates the physics that underlies the correlation between the anomalous magnetic moment and the Sivers effect for a given quark flavor.
