Descrizione

Recently, a large statistics sample of approximately 3*10^7 decays of the eta meson have been collected with the WASA detector at COSY using the pd ->3He reaction at beam kinetic energy 1 GeV. This data are being used to study the not so rare eta decays involving charged pions, like pi+ pi- pi0 . This decay proceeds mainly via a strong isospin violating contribution, where the decay width is proportional to the light quark mass difference squared, (md - mu)^2. Preliminary results of the analysis are presented. Supported by BMBF, Wallenberg Foundation and Uddeholms Forskarstipendium.
