Vector Dominance and Meson Photoproduction

Abstract

In this note we assume that matrix elements of currents are dominated by vector-meson intermediate states. This assumption is then used to relate pseudoscalar-meson photoproduction to the (strong-interaction) production of vector mesons. Numerical comparison is hindered by the lack of "overlapping" data for the above two reactions, but predictions appear to be in rough agreement with extrapolated data for photoproduction of $K\text{'}\mathrm{s}$ and $\pi \text{'}\mathrm{s}$. If valid, this vector dominance assumption could be a useful tool for high-energy photoproduction prediction.
