Exotic QQ$\overline{q}\overline{q}$ states in QCD
QCD contains stable four-quark $QQ \overline{qq}$ hadronic states in the limit where the heavy quark mass goes to infinity. (Here $Q$ denotes a heavy quark, $\overline{q}$ a light antiquark and the stability refers only to the strong interactions.) The long-range binding potential is due to one-pion...
