Abstract
We confirm the existence of the two I-G(J(PC)) = O+(O++) resonances f( 0)(1370) and f(0)(1500) reported by us in earlier analyses. The analys is presented here couples the final states pi(0) pi(0) pi(0), pi(0) pi (0) eta and pi(0) eta eta of ($) over bar pp annihilation at rest. It is based on a 3 x 3 K-matrix. We find masses and widths of M = (1390 /- 30) MeV, Gamma = (380 +/- 80) MeV; and M = (1500 +/- 10) MeV, Gamma = (154 +/- 30) MeV, respectively. The product branching ratios for th e production and decay into pi(0) pi(0) and eta eta of the f(0)(1500) are (1.27 +/- 0.33) . 10(-3) and (0.60 +/- 0.17) . 10(-3), respectivel y.
