To the nature of $χ_{c 2} (2 P)$

Abstract

We expect that $B R (χ_{c 2} (2 P) \to g l u o n g l u o n) ≳ 2%$ 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 $χ_{c 2} (2 P)$ decaying to the light hadrons. We also discuss the detection possibilities of these decays.
