Abstract

The exclusive photoproduction reaction γp→ϒ(1 S)p has been studied with the ZEUS detector in ep collisions at HERA using an integrated luminosity of 468 pb−1. The measurement covers the kinematic range60<W<220 GeV and Q2<1 GeV2, where W is the photon–proton centre-of-mass energy and Q2 is the photon virtuality. The exponential slope, b, of the t dependence of the cross section, where t is the squared four-momentum transfer at the proton vertex, has been measured, yielding b = 4.3{+2.0 =1.3}(stat.){+0.5 -0.6}(syst.) GeV-2. This constitutes the first measurement of the t dependence of the γp→ϒ(1 S)p cross section.
