文摘The effect of higher dimensional quark-gluon condensates on the effective quark-antiquark potential is investigated.In this scenario,cc and bb 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.
