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

Abstract

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