Vector-Meson-Dominance Predictions on Inelastic Electron-Proton Scattering

Abstract

We present predictions of the (recently proposed) vector-meson-dominance model for inelastic electronproton scattering in a manner that can be compared directly with forthcoming experimental data. For large scattering angles ($\theta =18\mathrm{}°-34\mathrm{}°$), a spectacular variation is predicted in $\frac{d^2\sigma }{d\Omega d{E}^{\prime }}$ as a function of the missing mass or $q^2$, in sharp contrast with the published 6° data, which exhibit a very weak $q^2$ dependence. We also give our $\nu W_2$ and $\left(\frac{q^2}{\nu }\right)W_1$ as functions of $\frac{\nu }{q^2}$.
