Remarks on the ηππ(K\(\bar K\)) mass spectrum for\(J/\psi \to \gamma \eta \pi \pi \left( {\gamma K\bar K} \right)\)

Article

Summary

It is pointed out that i) the observed structure of the ηππ mass distribution for J/Φ→γηππ may be interpreted in terms of the effects due to the I++ mesons E(1420) and Ē(1710) which consist of the s\(\bar s\) state and glueball and ii) the peaks observed in the K\(\bar K\) mass spectrum for\(J/\psi \to \gamma K\bar K\) can also be understood as the effects of resonances withJPC=0++ or 2++.
