Is X(3872) a possible candidate of hybrid meson

The associate productions of X(3872) and J/\psi in hadron collisions and flavor independence of hadrons in ee^+\to X(3872)+hadrons and the decays X(3872)\to \gamma+hadrons are discussed. It is pointed out X(3872)\to J/\psi+\sigma could be a significant decay channel.Comment: 13 page
