Abstract: (Elsevier)
In this paper we present evidence for a constructive interference effect between the 2π decays of the ω and the ϱ o observed in the reaction π − p → p π + π − π − at 3.9 GeV/ c . From analysis of the π + π − mass spectrum, we obtain for the branching ratio Γ ( ω → π + π − )/ Γ ( ω → π + π − π 0 ) a lower limit of 1.1% at the 95% confidence level.- pi- p: interaction
