image and image photoproduction measurements with PHENIX Original Research Article

J/ψ and e+e− photoproduction measurements in ultra-peripheral Au+Au collisions at View the MathML source with the PHENIX experiment are presented [PHENIX Collaboration, A. Afanasiev et al, arXiv:0903.2041 (2009) and references therein]. The triggered events correspond to those accompanied with forward neutron emission from the Au* dissociation. J/ψ and high-mass e+e− cross sections and pT distributions are consistent with various theoretical calculations.
