Wiedner, U

The Crystal Barrel experiment has been constructed and installed at the Low Energy Antiproton Ring (LEAR) at CERN. It has been fully operational since late 1989. In this talk, recent results of meson spectroscopy in [bar p]p annihilations are presented. The main emphasis is on all-neutral annihilations, the study of the strange quark content of the proton, and the investigation of the decay mode of [eta] particles. A 2[sup ++] resonance decaying into [pi][sup 0][pi][sup 0] at a mass of 1515 [+-] 10 MeV, with a width of 120 [+-] 10 MeV, has been seen in a 3[pi][sup 0] final state. 14 refs., 18 figs.
