Abstract
The BES experiment at the Beijing electron-position collider has obser ved the xi(2230) signal in pi(+)pi(-), K+K-, (KSKSO)-K-O, and <(p)over bar p> final states with 4.6 sigma, 4.1 sigma, 4.0 sigma, and 3.8 sig ma statistical significance, respectively. The new observations of two nonstrange decay modes of xi --> pi(+)pi(-) and <(p)over bar p> are i mportant evidence for the glueball interpretation of the xi(2230).
