Abstract

A study of the Okubo-Zweig-Iizuka (OZI) rule has been performed in a high-energy photon beam by comparing the production ratios of exclusive meson final states. Measurement of the ratio $\frac{σ (γ A \to φ π^{+} π^{-} A)}{σ (γ A \to ω π^{+} π^{-} A)} = 0.10 \pm 0.02$ is evidence that the OZI rule does not suppress this photoproduction reaction to the extent observed in $φ$ decays and in production by hadrons. The ratios of other exclusive photoproduction reactions are also presented.
