A consideration on the search for hybrid\(c\bar cg\) mesonsmesons

Summary

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\(c\bar c\) mesonsχ_c and the ground-state hybrid\(c\bar c\) mesonsχ_cg.
