- W2797188367 abstract "The confirmation of charged charmonium-like states indiates that heavy quark molecules should exist. We here discuss the possibility of a molecule state with $J^{PC}=3^{-+}$. In a one-boson-exchange model investigation for the S wave $C=+$ $D^*bar{D}_2^*$ states, one finds that the strongest attraction is in the case $J=3$ and $I=0$ for both $pi$ and $sigma$ exchanges. Numerical analysis indicates that this hadronic bound state might exist if a phenomenological cutoff parameter around 2.3 GeV (1.5 GeV) is reasonable with a dipole (monopole) type form factor in the one-pion-exchange model. The cutoff for binding solutions may be reduced to a smaller value once the $sigma$ exchange contribution is included. If a state around the $D^*bar{D}_2^*$ threshold ($approx$4472 MeV) in the channel $J/psiomega$ (P wave) is observed, the heavy quark spin symmetry implies that it is not a $cbar{c}$ meson and the $J^{PC}$ are likely to be $3^{-+}$." @default.
