Description

Utilizing the analytic properties of a heavy photon forward Compton scattering amplitude, we derive a sum rule which connects the hadron electromagnetic formfactors with the differential cross section of the electroproduction process on a hadron. For the case of small transferred momenta, it can be expressed as a relation of the radius and eventually the electromagnetic moment with the integral over the total hadron photoproduction cross section
