Is X(3872) a possible candidate of hybrid meson

Abstract

The associate productions of X(3872) and J/ψin hadron collisions and flavor independence of hadrons in ee^+\to X(3872)+hadrons and the decays X(3872)\to γ+hadrons are discussed. It is pointed out X(3872)\to J/ψ+σcould be a significant decay channel.
