Abstract

The associated production of a J/\ensuremathψ and a photon in photon-hadron collisions is considered and shown to be a good probe of the presence of color-octet-mediated channels in quarkonia production, as predicted by the factorization approach within NRQCD. Total and differential cross sections for photoproduction at fixed target experiments and at DESY HERA are presented. Associated J/\ensuremathψ+\ensuremathγ production at hadron colliders is briefly discussed.
