Abstract

Elastic photoproduction of φ mesons from the proton was measured for the first time up to -t = 4 GeV2. Below -t ≈ 1 GeV2, the data cannot distinguish between the Pomeron exchange and the two-gluon exchange models. Above -t ≈ 1.8 GeV2, the data ruled out the diffractive Pomeron and strongly favored its two-gluon realization.
