英文摘要: The effect of higher dimensional quark-gluon condensates on the effective quark-antiquark potential is investigated. In this scenario, c (c) over bar and b (b) over bar spectra are studied. It is shown that the vacuum condensates of the d = 5 and d = 6 operators, where d denotes the dimension of the operator, still cause notable effects. The perturbative loop contributions from the s-channel scattering and t-channel annihilation processes to the potential are almost the same. These contributions are opposite in sign to the non-perturbative contributions of the d = 4 operator condensates.
