On the nature of χ_(c2)(2P):two-gluon decay
摘    要:We expect that BR(χ_(c2)(2P)→gluongluon) ≥2% if the Particle Data Group as well as the Ba Bar and Belle collaborations have correctly identified the state. In reality, this branching ratio corresponds to the one forχ_(c2)(2P) decaying into light hadrons. We also discuss the detection possibilities of these decays.
