Abstract
Heavy hadrons are analyzed in a random and dilute gas of instantons. W e derive the instanton-induced interactions between heavy and light-qu arks at next to leading order in the heavy quark mass and in the plana r approximation, and discuss their effects on the hadronic spectrum. T he role of these interactions in the formation of exotic hadrons is al so discussed.
