Abstract

Vector-dominance predicts a relation between the combined asymmetry in π⁺ and π^- photoproduction by polarized photons and the cross section for producing transversely polarized vector mesons. We predict that at high energies and t=-m_π² this relation will be violated by the data. We explain this expected failure by a strong mass dependence of the mechanism which governs the forward amplitudes for these processes.
