Compton scattering and vector-meson photoproduction
A recently proposed model for Compton scatterlng and deep inelastic electroproduction is extended to describe vector-meson photoproduction. Vector- meson dominance is formulated covariantly in terms of invariant amplitudes, and the assumption of a smooth zero-mass limit leads to definite relations between the amplitudes for the different processes. The breaking of simple vector dominance observed in these reactions is accounted for by an additiona1 mass dependence. A good fit to the vector photoproduction data is obtained. (auth)
