Ultra-peripheral Au+Au collisions at PHENIX

Research output: Contribution to conferencePaper

Abstract

Ultra-peripheral collisions (UPC) of heavy-ions involve long range electromagnetic interactions at impact parameters twice larger than the nuclear radius, where no nucleonnucleon collisions occur. The first measurement of photoproduction of J/ψ and of two-photon production of high-mass e +e-. pairs in ultra-peripheral nucleus-nucleus interactions will be presented, using Au+Au data at √sNN = 200 GeV. The measured cross sections at midrapidity are consistent with various theoretical predictions. [1].
