Mass Formulas and the Algebraic Structure of Superconvergence Relations
Frederick J. Gilman, Haim Harari · Physical Review Letters · 1967
Sets of $t=0$ current-algebra and superconvergence sum rules are treated as equations in the coupling constants and masses of states which are assumed to dominate the sum rules. The solutions of these sets lead to new mass relations among particles of different spins and parities. The algebraic structure of the sum rules and their solutions is discussed.
