Abstract
The leading nonperturbative QCD corrections to the one gluon exchange quark-quark, quark-antiquark and pair-excitation potentials are derived by using a covariant form of nonlocal two-quark and two-gluon vacuum expectation values. Our numerical calculation indicates that the correction of quark and gluon condensates to the quark-antiquark potential improves the heavy quarkonium spectra to some degree.
