Abstract

Some recent progresses in our understanding of penta-quark components in baryons is briefly reviewed. The diquark cluster picture for the penta-quark components in baryons gives a natural explanation not only to the empirical indications for a positive strangeness magnetic moment μ_s and positive strangeness radius of the proton but also the longstanding mass-reverse problem of N*(1535), N*(1440) and Λ*(1405) resonances as well as the unusual decay pattern of the N*(1535) resonance. Evidence supporting this picture from available BES data on J/ψ decays is pointed out.
