A short note on \(q\bar qg\) hybrid assignment for \(X(1812)\to \omega\phi\)

Abstract

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.
