Higher order QED in high mass e+ e- pairs production at RHIC
Anthony J. Baltz🇺🇸 · Joakim Nystrand🇳🇴
Abstract
Lowest order and higher order QED calculations have been carried out for the RHIC high mass e+ e- pairs observed by PHENIX with single ZDC triggers. The lowest order QED results for the experimental acceptance are about two standard deviations larger than the PHENIX data. Corresponding higher order QED calculations are within one standard deviation of the data.
