Light-meson spectroscopy and combined analysis of processes with pseudoscalar mesons
Original language description
The status and parameters of the scalar, vector, and tensor mesonic resonances are obtained in the multichannel analysis of processes pi pi -> pi pi, K (K) over bar, eta eta, and eta eta' and compared with other results. For example, we obtained the f(0)(600) meson with mass 774 +/- 15 MeV and width 988 +/- 36 MeV (the pole position on sheet II is 596 - i494 MeV) and the first rho-like meson with mass 1275 +/- 32 MeV and total width 304 +/- 24 MeV, which differ significantly from the mean value 1459 +/-11 MeV cited in the Particle Data Group tables. Spectroscopic implications from results of these analyses and possible classification of the resonance states in terms of the SU(3) multiplets are also discussed.
