Coupled channel analysis of overlinepp annihilation into π0π0π0, π0ηη and π0π0η
Abstract
We confirm the existence of the two IG( JPC) = 0 +(0 ++) resonances f0(1370) and f0(1500) reported by us in earlier analyses. The analysis presented here couples the final states π0π0π0, π0π0η and π0ηη of overlinepp annihilation at rest. It is based on a 3 × 3 K-matrix. We find masses and widths of M = (1390±30) MeV, Γ = (380±80) MeV; and M = (1500±10) MeV, Γ = (154 ± 30) MeV, respectively. The product branching ratios for the production and decay into π0π0 and ηη of the f 0(1500) are (1.27 ± 0.33) · 10 -3 and (0.60 ± 0.17) · 10 -3, respectively.
