   • Pertinence: a2 photoproduction cross section
   • Abstract: We examine the negative 3π final state produced in association with Δ++(1232) in the reaction γp→Δ++π+π-π- at an incident photon energy of 19.3 GeV. The most prominent enhancement in the 3π spectrum occurs at a mass and with a width consistent with the parameters of the a2(1320). This identification is confirmed by the various angular distributions. The a2 production cross section, corrected for efficiencies and alternate a2 decay modes, is 0.45±0.05 μb.

   • Pertinence:
   • Abstract: Evidence is presented for the charge-exchange photoproduction, in two distinct reactions, of an isovector ρπ state of mass ∼1775 MeV. Results of an analysis of the decay-angular distributions are also presented, from which it is concluded that JP=1-, 2-, or 3+.
