| 英文摘要 | Based on 9.0 x 10(6) J / psi data collected at BES, a systematic physics analysis has been performed. We confirmed the existence of xi(2230) in J / psi --> gamma K (K) over bar and observed for the first time the non-strange decay modes xi(2230) --> pi(+) pi(-), pi(0)pi(0) and pp. The resonance and polarization parameters of f(0)(980) and f(2)(1270) were measured. The moment study on J/psi-->gamma K+K- revealed that the controversial f(J)(1710) is composed of two states, a 0(++) and a 2(++). With the help of PWA method, the spin-parities for eta(1440) and f(0)(1500) were obtained, and their main decay modes were found. |
