In this paper we have reported some arguments on the search for charmonium hybrid meson\(c\bar cg\). Referring to our previous work on light-quark mesons, we have discussed the possible existence of hybrid\(c\bar cg\) mesons and studied the decay properties of their ground state into the OZI-allowed channels and the OZI-forbidden\(c\bar c\)-triggered channels. We have also discussed their radiative-decay properties and pointed out the possibility of the mixing effect between theP-wave\(c\bar c\) mesonsχc and the ground-state hybrid\(c\bar c\) mesonsχcg.
