Abstract
The pi(+)pi(-)pi(0), K(+)K(-)pi(0) and K(+/-)K(0)pi(-/+) final states produced by (p) over barp annihilation at rest at three different hydrogen target densities have been analyzed in the frame of a coupled channel analysis together with pipi, piK and K (K) over bar scattering data. The percentages of the different partial waves, the branching ratios and the parameters (masses, widths, pipi and K (K) over bar partial widths) of all the involved resonances (J(P) = 0(+), 1(-), 2(+)) have been measured. The main results on meson spectroscopy concern the determination of the Gamma(K (K) over bar)/Gamma(pipi) ratio for f(0)(1370) and f(0)(1500) (Gamma(K (K) over bar)/Gamma(pipi) = 0.91 +/- 0.20 and Gamma(K (K) over bar)/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 rho signals associated to rho(1450) and rho(1700) (M = 1182 +/- 30 MeV; Gamma = 389 +/- 20 MeV and M = 1594 +/- 20 MeV; Gamma = 259 +/- 20 MeV respectively).
