Description
Heavy nuclei at collider energies are a source of high-energy Weizsäcker-Williams photons. This photon flux may be utilized to study high-energy photon-nucleus interactions. We will first discuss the coherent diffractive production of heavy vector mesons on nuclear targets and show how it probes the unintegrated glue of the nucleus in the saturation domain. We present our calculations for rapidity distributions of exclusive coherent J/Ψ and Υ mesons. Then we will turn to the gamma-gamma collisions and address the production of a pair of J/Psi's.
