    "abstract": "In the adiabatic approximation, most of the effects of quark-antiquark loops\non spectroscopy can be absorbed into a static interquark potential. I develop a\nformalism which can be used to treat the residual nonadiabatic effects\nassociated with the presence of nearby hadronic thresholds for heavy quarks. I\nthen define a potential which includes additional high energy corrections to\nthe adiabatic limit which would be present for finite quark masses. This\n\"improved\" potential allows a systematic low energy expansion of the impact of\nthresholds on hadronic spectra.",
