Abstract

BES Collaboration has recently observed an enhancement near the ωϕ\omega\phi threshold in the double OZI suppressed decay J/ψ→γωϕJ/\psi \to\gamma\omega\phi. This ωϕ\omega\phi enhancement is probably due to a new JPC=0++J^{PC}=0^{++} X(1812) state. We discuss a possible assignment that the X(1812) is a 1/2(uuˉ+ddˉ)g 1/\sqrt{2}(u\bar u+d\bar d)g (or ssˉgs\bar sg) hybrid meson. We suggest further measurements to test these assignments.
