Phi-meson photoproduction from nuclei

Abstract

We study coherent and incoherent phi-meson photoproduction from nuclei. The available data are analyzed in terms of single and coupled channel photoproduction. It is found that the data on coherent photoproduction can be well reproduced within a single channel optical model and show only little room for omega-phi mixing. These data indicate a normal distortion of the phi-meson in nuclei, which is compatible with the results obtained through the vector meson dominance model. The data on incoherent phi-meson photoproduction show an anomalous A-dependence resulting in a very strong phi-meson distortion. These data can be explained by a coupled channel effect through the dominant contribution from the omega -> phi or pi -> phi transition or, more speculative, through the excitation of a cryptoexotic B_phi-baryon.
