摘要

We investigate instanton effects on the heavy-quark potential,including its spin-dependent part,based on the instanton liquid model.Starting with the central potential derived from the instanton vacuum,we obtain the spin-dependent part of the heavy-quark potential.We discuss the results of the heavy-quark potential from the instanton vacuum.Finally,we solve the nonrelativistic two-body problem,associated with the heavy-quark potential from the instanton vacuum.The instanton effects on the quarkonia spectra are marginal but are required for quantitative description of the spectra.
