Query: A short note on $q\bar qg$ hybrid assignment for $X(1812)\to \omega\phi$   BES Collaboration has recently observed an enhancement near the $\omega\phi$
threshold in the double OZI suppressed decay $J/\psi \to\gamma\omega\phi$. This
$\omega\phi$ enhancement is probably due to a new $J^{PC}=0^{++}$ X(1812)
state. We discuss a possible assignment that the X(1812) is a $
1/\sqrt{2}(u\bar u+d\bar d)g$ (or $s\bar sg$) hybrid meson. We suggest further
measurements to test these assignments.
