Two-pion spectra for the reaction pi(-)p ->pi(0)pi(0)n at a pion momentum of 38 GeV/c and combined analysis of GAMS, crystal barrel, and BNL data

We perform a K-matrix analysis of IJ(PC) = 00(++), 10(++), 02(++), and 12(+) meson partial waves using GAMS data on pi(-)p-->pi(0)pi(0)n, eta eta n, eta eta'n that are supplemented with BNL data on pi(-)p --> K (K) over bar n and Crystal Barrel data on p (p) over bar (at rest) --> pi(0)pi(0)pi(0), pi(0)eta eta, pi(0)pi(0)eta. The positions of the amplitude poles (physical resonances) are determined, together with the positions of the K-matrix po les (bare states) and the values of bare-state couplings to two-meson chann els. The nonet classification of the bare states found in the present analy sis is discussed. (C) 2000 MAIK "Nauka/Interperiodica".
