摘要：

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=-mπ2 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. © 1969.
