| 英文摘要 | The open-charm strong decays of higher charmonium states up to the mass of the 6P multiplet are systematically studied in the P-3(0) model. The wave functions of the initial charmonium states are calculated in the linear potential and screened potential quark models. The decay widths for most of the well-established charmonium states above the open-charm thresholds can be reasonably described. By comparing our quark model calculations with the experimental observations we also discuss the nature of some of the newly observed charmonium-like states. It is found that (i) the psi(4415) may favor the psi(4S) or psi(1) (3D) assignment. There may exist two highly overlapping vector charmonium states around 4.4 GeV; (ii) in the LP model the J(PC) = 1(--) Y(4660) resonance and the J(PC) = 0(++) X(4500) resonance may be assigned as the psi(5S) and chi(c0)(4P), respectively; (iii) the newly observed state X* (3860) can be assigned as the chi(c0)(2P) state with a narrow width of about 30 MeV; (iv) it seems to be difficult to accommodate the X(4140) and X(4274) states in the same potential model as excited chi(c1) states; (v) the X(3940) resonance can be assigned as the eta(c)(3S) state; (vi) the vector charmonium-like states Y(4230/4260, 4360) and scalar X(4700) cannot be described by any conventional charmonium states self-consistently in our model. |
