abstract:
The pi+pi−pi0, K+K−pi0 and K±K0pi∓ final states produced by pbar-p annihilation at rest at three different hydrogen
target densities have been analyzed in the frame of a coupled channel analysis together with pi-pi and pi-K scattering data.
Here we present the main results which concern masses, widths, pi-pi and K-Kbar partial widths of all the involved resonances
(J P = 0+, 1−, 2+), the direct determination of Γ(Kbar-K)/Γ(pi-pi) ratio for f0(1370) and f0(1500), the determination of a0(1300) parameters (M = 1303 ± 16 MeV; Γ = 92± 16 MeV)
and the observation of two different high mass ρ signals associated to ρ(1450) and ρ(1700) (M = 1182 ± 30 MeV;
Γ = 389 ± 20 MeV and M = 1594 ± 20 MeV; Γ = 259 ± 20 MeV, respectively).
