The Exotic Atoms of QCD: Glueballs, Hybrids and Baryonia

  • T. Barnes
Part of the Ettore Majorana International Science Series book series (EMISS, volume 23)


In these three lectures I review the theoretical basis underlying the expected “exotic” states in QCD, the theory of quarks and gluons. The first lecture is an historical introduction to QCD, meant to motivate it to the non-specialist. The second lecture is a critical review of the two most important models used by theorists to try to understand unusual quark and gluon states — the MIT bag model and QCD on a lattice. Recent developments in both models of possible experimental relevance are particularly emphasized. Finally, in. the third lecture I discuss the status of three candidate “exotic” states seen in ψ radiative decays, the i(1440), θ(1700) and ξ(2220), and review theorists’ suggestions of what these states might be.
