Abstract

We report the first measurement of the photoproduction cross section of the phi meson in its neutral decay mode in the reaction gamma p -> p phi(KSKL). The experiment was performed with a tagged photon beam of energy 1.6 pK(S)X to be K-L. The presented results significantly enlarge the existing data on phi photoproduction. These data, combined with the data from the charged decay mode, will help to constrain different mechanisms of phi photoproduction.
