| 英文摘要 | We propose two models for a heavy-quark potential with possible natural QCD interpretations. The potentials approach the two-loop perturbative QCD formula at short distance and a linear confining potential at large distance, and their predicted ccBAR and bbBAR spectra all fit the data very well for LAMBDA(MSBAR) in the range 100-500 MeV, where MSBAR denotes the modified minimal subtraction scheme. Furthermore, the potentials are described directly in coordinate space with explicit LAMBDA(MSBAR) dependence so that they are convenient for practical calculations. Some of their phenomenological predictions are given, especially, in the picture regarding a confining potential as a scalar exchange. The predicted masses of psi (1 P-1(1)) and gamma(1 P-1(1)) are higher than the center-of-gravity values of the 1 3P(J) states by 0.9-1.8 MeV and 0.4-0.7 MeV, respectively, for LAMBDA(MSBAR) in the range 100-200 MeV. |
