Abstract

We expect that BR(χc2(2P)→gluon gluon)≳2%BR(\chi_{c2}(2P)\to gluon\, gluon)\gtrsim 2 \% if Particle Data Group as well as BaBar and Belle collaboration correctly identified the state. In reality, this branching ratio corresponds to the one for χc2(2P)\chi_{c2}(2P) decaying to the light hadrons. We also discuss the detection possibilities of these decays.

Keywords

charmonium chi_c2(2P) branching ratio gluon decay light hadrons detection
