Diffractive J/ψ and continuum e+e− pair production in PHENIX Ultraperipheral Collisions

We report results on high energy photoproduction from the PHENIX experiment. Using Run 4 Au-Au data taken with an ultra-peripheral trigger (requiring a rapidity gap in 3.0⩽η⩽3.9). We find 10±3 candidates for diffractive J/ψ photoproduction and of order 40 candidates for continuum e+e− photoproduction in the mass range mee⩾1.8GeV/c2. We then discuss prospects and rates for hard photoproduction at the LHC with Pb-Pb beam collisions and p-Pb.
