DOIAbstract
The π+π−π0, K+K−π0 and K±K0π∓ final states produced by annihilation at rest at three different hydrogen target densities have been analyzed in the frame of a coupled channel analysis together with ππ and πK scattering data. Here we present the main results which concern masses, widths, ππ and partial widths of all the involved resonances (JP=0+,1−,2+), the direct determination of ratio for f0(1370) and f0(1500) ( and , respectively), 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)
