Abstract

Photoproduction of neutral pions has been studied with the CBELSA/TAPS detector in the reaction gamma p -> p pi(0) for photon energies between 0.85 and 2.50 GeV. The pi(0) mesons are observed in their dominant neutral decay mode: pi(0) -> gamma gamma. For the first time, the differential cross sections cover the very forward region, theta(c.m.) < 60 degrees. A partial-wave analysis of these data within the Bonn-Gatchina framework observes the high-mass resonances G(17)(2190), D(13)(2080), and D(15)(2070).
