Sum rules are derived relating meansquared charge radii in the case of
pseudoscalar meson, Dirac meansquared radii and anomalous magnetic moments in
the case of (1/2)^{+} baryon, and finally sum of ratios of the fourth
power of quark charges to the squared quark masses in the case of photon, with
convergent integrals over the hadron photoproduction total crosssections on
pseudoscalar mesons, octet baryons and over gg® 2 jets crosssection, respectively.
As a byproduct, chains of inequalities for
corresponding total photoproduction crosssections on meson and baryons in
finite energy region, to be valid on an average, are also derived.
