Abstract

The partial wave analysis of the reaction p̄p → π⁺π^-π⁰ at rest has been performed for the first time by using high-statistics data sets collected in hydrogen targets at three different densities. The different mixtures of partial waves corresponding to our samples allow a reliable determination of each contribution. This technique is crucial in the identification of the exotic candidate f₂(1565) which can be produced by ¹S₀, ³P₁ and ³P₂ initial states. The amplitude analysis was performed in the frame of the K-Matrix and P-Vector approach. It requires the presence of the exotic candidates f₀(1500) and f₂(1565) with the following masses and total widths: (1449 ± 20)MeV, (114 ± 30)MeV and (1507 ± 15)MeV, (130 ± 20)MeV respectively. In addition to f₀(980), f₀(1300) f₂(1270) and ρ(770), a clear evidence of I = 1, J^P = 1^- signal, which we identify with ρ(1450), is obtained.
