Abstract
Consequences of Weinberg's postulative assumption requiring that rapidly growing pole terms which contribute to the forward-scattering amplitude must cancel among themselves and not with the continuum in order to preserve the Regge behavior are examined within the framework of dispersion relations. Twice-subtracted dispersion relations with soft-meson theorems as known subtraction constants are used to determine the transformation properties of the SU(3)⊗SU(3)-symmetry-breaking term in the mass spectrum of hadrons.
