Production of a Q^2\bar{Q}^2 state in J/ψ\to γωφ

The resonance X(1810) discovered in $J/\psi\to \gamma\omega\phi$ by BESII is considered as a candidate of $0^{++}$ $Q^2\bar{Q}^2$ state. This model predicts that $X\to\omega\phi, K^* K^*$ are the two dominant decay channels and $X\to KK, \eta\eta, \eta\eta'$ are suppressed. The cross sections of $\gamma\gamma\to X\to \omega\phi, K^* K^*$ are estimated.
