| 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.

| Abstract: | We expect that BR(χc2(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 χc2(2P) decaying into light hadrons. We also discuss the detection possibilities of these decays. |
