    Nonperturbative QCD Vacuum Effects in Nonlocal Quark Dynamics

    A straightforward calculation reveals the essentially nonlocal character of the leading heavy QQˉQ\bar{Q} interaction arising from nonperturbative gluon field correlations in the model of a fluctuating QCD vacuum. In light of this quarkonium spin splitting ratio predictions which have supported the scalar confinement ansatz are reconsidered as a specific example of possible consequences for spectroscopy.Comment: Latex, 9 page
