Studies of ξ(2230) in J/ ψ Radiative Decays
Abstract
The BES experiment at the Beijing electron-positron collider has observed the ξ(2230) signal in π+π-, K+K-, K0SK0S, and pp¯ final states with 4.6σ, 4.1σ, 4.0σ, and 3.8σ statistical significances, respectively. The new observations of two nonstrange decay modes of ξ-->π+π- and pp¯ are important evidence for the glueball interpretation of the ξ\(2230\).
