Sum rules for total cross sections of hadron photoproduction on ground state $1/2^{+}$ octet baryons

Sum rules are derived relating Dirac mean square radii and anomalous magnetic moments of various couples of the ground state $1/2^{+}$ octet baryons with the convergent integral of the difference of hadron photoproduction total cross-sections on the baryons. The chain of inequalities for corresponding total cross-sections has been found from those sum rules.
