Exotic QQ States in QCD
Aneesh V. Manohar, Mark B. Wise
Abstract
We show that QCD contains stable four-quark QQ hadronic states in the limit where the heavy quark mass goes to infinity. (Here Q denotes a heavy quark, a light antiquark and the stability refers only to the strong interactions.) The long range binding potential is due to one pion exchange between ground state Q mesons, and is computed using chiral perturbation theory. For the Q=b, this long range potential may be sufficiently attractive to produce a weakly bound two meson state.
