Spin-Parity Analysis of the Final State pi+ pi- pi0 frompbar p Annihilation at Rest in Hydrogen Targets at Three Densities

he partial wave analysis of the reaction (p) over bar p --> pi(+)pi(-)pi(0) 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 f(2)(1565) which can be produced by S-1(0), P-3(1) and P-3(2) 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 f(0)(1500) and f(2)(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 f(0)(980), f(0)(1300) f(2)(1270) and rho(770), a clear evidence of I = 1, J(p) = 1(-) signal,which we identify with rho(1450), is obtained.
