Abstract

In the adiabatic approximation, most of the effects of q (q) over bar loops on spectroscopy can be absorbed into a static interquark potential. I develop a formalism which can be used to treat the residual nonadiabatic effects associated with the presence of nearby hadronic thresholds for heavy quarks. I then define a potential which includes additional high energy corrections to the adiabatic limit which would be present for finite quark masses. This "improved" potential allows a systematic low energy expansion of theimpact of thresholds on hadronic spectra. [S0556-2821(99)06315-8].
