Beschreibungen/Notizen

• Here, the STAR Collaboration reports on the photoproduction of π+π- pairs in goldgold collisions at a center-of-mass energy of 200 GeV/nucleon-pair. These pion pairs are produced when a nearly-real photon emitted by one ion scatters from the other ion. We fit the π+π- invariant mass spectrum with a combination of 0 and ! resonances and a direct π+π- continuum. This is the first observation of the ! in ultra-peripheral collisions, and the first measurement of ρ - ω interference at energies where photoproduction is dominated by Pomeron exchange.
