Hadronic decays of the ω meson

The WASA detector at COSY have measured the ω meson in the reaction channel p + d → 3He + ω. With this data we aim to study two hadronic decays of the ω meson, ω → π+ π− π0 and ω → π+ π−. The goal for the π+π−π0 study is to extract a Dalitz plot of the final state pions. An high statistics Dalitz plot would enable tests of theoretical predictions for the decay mechanism. The goal for the π+π− study is to perform an independent verification of the branching ratio.
