Abstract：
We expect that BR( χ _c2(2 P)→ gluongluon)≥ 2% if the Particle Data Group as well as the BaBar and Belle collaborations have correctly identified the state. In reality, this branching ratio corresponds to the one for χ _c2(2 P) decaying into light hadrons. We also discuss the detection possibilities of these decays.
- charmonium,
- branching ratio,
- two-gluon decay mode
