Abstract We study the hadronic decay of q $$\bar q$$ g hybrid mesons. To that aim we establish the connection between the diatomic-molecule like wave functions and the standard q $$\bar q$$ g wave functions. We show that inSU(6) approximation TE hybrids cannot decay intoPP, PV, VV channels while TM hybrids are weakly coupled to ψγ. Hence only TE-TM mixed hybrids are easy to see in ψ → γX. We show that hydrids are weakly mixed with quarkonia. We discuss the possible nature of the ξ(2.2) resonance and the ways of detecting exotic 1−+ q $$\bar q$$ g bound states.
