Abstract

Exclusive vector meson photoproduction, pp→ ppV and pp→ ppV occurs with significant rates at hadron colliders. The reaction can be used to study the gluon distribution of protons. Vector mesons may be produced with either proton as a target; because of interference between the two production channels, the p_T spectra of vector mesons produced in pp and pp collisions are quite different. Because of the unique event signature, vector meson photoproduction can be separated from hadroproduction events, despite the small ratio of cross sections. We consider production of J/ψ and Υ at RHIC, the Tevatron and the LHC.
