Nuclear shadowing and rho photoproduction

Abstract

Rho photoproduction on complex nuclei is re-examined using a generalised vector dominance model which succesfully predicts the observed nuclear shadowing in real photoabsorption and deep inelastic scattering. This model is shown to give a good fit to rho photoproduction data on both nucleons and complex nuclei, in which the well-known disagreement between the measured gamma-rho coupling and the gamma-rho coupling required by the simple vector dominance model is eliminated. The rho N total cross-sections required are similar to those predicted by the additive quark model; and the magnitude of the correction to simple vector dominance is consistent with that inferred from the analysis of real photoabsorption and deep inelastic scattering.
