英文摘要: On the basis of the recent results of xi(2230) --> pi(+)pi(-), p (p) over bar and xi(2230) --> K+K-, KsKs, measured by the BES Collaboration in J/psi radiative decays, combined with the PS185 experiment of p (p) over bar --> xi(2230) --> K (K) over bar, we argue that because of its very narrow partial decay widths to pi pi and K (K) over bar (less than 1 MeV), its large production rate in J/psi radiative decays (BR(J/psi --> gamma xi) > 2.3 x 10(-3) and its flavor-symmetric couplings to pi pi and K (K) over bar, the xi(2230) is very likely to be a J(PC) = (even)(++) glueball.
