Abstract：
We expect that BR(χ_c2(2P)→ 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(2P) decaying into light hadrons. We also discuss the detection possibilities of these decays.
- charmonium ,
- branching ratio ,
- two-gluon decay mode
