A short note on $q\bar{q}g$ hybrid assignment for $X(1812)\to \omega \varphi$

Abstract

BES Collaboration has recently observed an enhancement near the $\omega \varphi$ threshold in the double OZI suppressed decay $J/\psi \to \gamma \omega \varphi$. This $\omega \varphi$ 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 $s\bar{s}g$) hybrid meson. We suggest further measurements to test these assignments.
