Jpsi and dielectron photoproduction measurements with PHENIX

Understand

Jpsi and dielectron photoproduction measurements in ultra-peripheral Au+Au collisions at 200 GeV with the PHENIX experiment are presented.

• The triggered events correspond to those accompanied with forward neutron emission from the Au dissociation.
• Jpsi and high-mass dielectron cross sections and pT distributions are consistent with various theoretical calculations.
