Abstract

The CELSIUS/WASA experiment is now finishing its commissioning phase and has started regular data talcing in autumn 2001. Results from a first analysis of data samples from an experimental run at a beam energy of T _p = 1360MeV in September 2001 are presented. The results show the ability to tag π ⁰ and η production events. For 2π ⁰ production a large data sample exists. The 2π ⁰ and 3π ⁰ production processes will be important sources of background for the η decays. They have until now been poorly measured, if at all. at this energy. The decay η → γγ will be used for normalization of all other η decays and the η → 3π ⁰ decay will test the light quark mass ratio predicted by Chiral Perturbation Theory.
