Studies of {bold {xi}}(2230) in {ital J}/{bold {psi}} radiative decays

The BES experiment at the Beijing electron-positron collider has observed the {xi}(2230) signal in {pi}{sup +}{pi}{sup {minus}}, {ital K}{sup +}{ital K}{sup {minus}}, {ital K}{sup 0}{sub {ital SK}}{sup 0}{sub {ital S}}, and {bar {ital pp}} final states with 4.6{sigma}, 4.1{sigma}, 4.0{sigma}, and 3.8{sigma} statistical significances, respectively. The new observations of two nonstrange decay modes of {xi}{r_arrow}{pi}{sup +}{pi}{sup {minus}} and {bar {ital pp}} are important evidence for the glueball interpretation of the {xi}(2230). {copyright} {ital 1996 The American Physical Society.}
