abstract
Using the same quenched limit as input, we compare the charmonium spectra predicted by the coupled-channel model and the screened potential model in the mass region below 4 GeV, in which the contributions from decay channels involving P-wave (as well as even higher excited) D mesons can be neglected. We find that the two models have similar global features in describing charmonium spectrum since they embody the same effect of the vacuum polarization of dynamical light quark pairs. This agreement is encouraging for using the screened potential to further describe the mass spectrum of higher charmonium in the region above 4 GeV. Applying both models will be helpful to clarify the nature of the newly discovered "X,Y,Z" mesons in B-factories and other experiments. In particular, we show the S-wave decay coupling effect on lowering the $\chi_{c1}(2P)$ mass towards the $D\bar {D^*}$ threshold, in support of the assignment of the X(3872) as a $\chi_{c1}(2P)$-dominated charmonium state.

Unquenched calculation finds sizable 2P-1F mixing in charmonium with angles 7.5° and 15.4°, yielding predictions for two-photon and two-gluon decay widths.
The paper computes spectroscopic properties, OZI-allowed strong decays, and radiative transitions for the 2D and 1F charmonium states around 4 GeV to guide experimental searches.
Hadronic molecules serve as a framework for certain exotic heavy-quark states where nonrelativistic effective field theories enable predictions with controlled uncertainty.
