摘要

We expect that BR(Xc2(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 Xc2(2P) decaying into light hadrons.We also discuss the detection possibilities of these decays.
