Abstract

We discuss the associate production of a J/ψ meson and a photon at {Mathematical expression} (or pp) and ep colliders. By requiring the J/ψ to decay into an e+e- or μ+μ- pair, we end up with an exceptionally clean final state. Furthermore, in leading order it can only be produced via gluon fusion. This process can therefore serve as a very clean probe of the gluon densities inside the proton as well as the photon. Numerical results are presented for the tevatron {Mathematical expression} and HERA ep colliders.
