The production of φ mesons in the reaction e + p → e + φp ( gf → K + K − ) at a median Q 2 of 10 −4 GeV 2 h been studied with the ZEUS detector at HERA. The differential φ photoproduction cross section dσ dt has an exponential shape and has been determined in the kinematic range 0.1 < | t | < 0.5 GeV 2 and 60 < W < 80 GeV. An integrated cross sect σ γp → φp = 0.96±0.19 −0.18 +0.21 μ b has been obtained by extrapolating to t = 0. When compared to lower energy data the results show a weak energy dependence of both σ γp → φp and the slope of the t distribution. The φ decay angular distributions are consistent with s -channel helicity conservation. From lower energies to HERA energies, the features of φ photoproduction are compatible with those...
