Veneziano — Like Model for A Two-Current Amplitude
Some properties of the usual Veneziano beta-function are reviewed. A model is then constructed for an amplitude involving two charged isovector currents. It is found that when one incorporates certain desirable features, in particular the correct Fubini-Gell-Mann fixed pole at j=l, the model automatically satisfies the Bjorken scaling law. It is shown how the model may be extended to describe deep inelastic electron-proton scattering.
