摘要

The pi(+)pi(-)pi(0), K(+)K(-)pi(0) and K(+/-)K(0)pi(double dagger) final states produced by p p annihilation at rest at three different hydrogen target densities have been analyzed in the frame of a coupled, channel analysis together with pipi and piK scattering data. Here we present the main results which concern masses, widths, pi and K (K) over bar partial widths of all the involved resonances (J(P) = 0(+), 1(-), 2(+)), the direct determination of Gamma(KK) / Gamma(pipi) ratio for f(0) (1370) and f(0) (1500) (Gamma(KK) / Gamma(pipi) = 0.91 +/- 0.20 and Gamma(KK) / Gamma(pipi) = 0.25 +/- 0.03, respectively), the determination of a(0) (1300) parameters (M = 1303 +/- 16 MeV, Gamma = 92 +/- 16 MeV) and the observation of two different high mass p signals associated to p(1450) and p(1700) (M = 1182 30 MeV, Gamma = 389 +/- 20 MeV and M 1594 +/- 20 MeV; Gamma = 259 +/- 20 MeV, respectively).
