| Description/Abstract | One of the most exciting developments in the physics of the 20th Century is the proposal that locally gauge invariant groups describe the strong, electromagnetic and weak interactions. SU(2)/sub L/ x U(1) the electroweak group has had enormous successes including the recent discovery of the W/sup +-/ and Z/sup 0/. In the case of strong interactions, Quantum Chromodynamics is built upon the local gauge invariance of SU(3)/sub color/ which gives rise to the eight massless spin 1 gauge bosons which carry color called gluons. The colored quarks are then added to yield Quantum Chromodynamics (QCD). Although there have been many dynamical and static successes of QCD, there has been one important missing link in QCD which casts a dark shadow over it and SU(3)/sub color/. Let us assume the strong interactions are described by locally gauge invariant SU(3)/sub color/ in a pure Yang Mills theory. Then if we consider the effects of confinement one is inescapably led to the existence of glueballs (multigluon resonant states). Experimentally we found vast numbers of q anti q states and qqq states but until recently no convincing evidence for glueballs. Fortunately recent work has led to the discovery of glueballs provided one assumes the following two simple input axioms: (1) QCD is correct and (2) the OZI (or Zweig) Rule is universal for weakly coupled glue in disconnected Zweig diagrams where the disconnection is caused by creation or annihilation of new flavors of quarks. There are other glueball candidates found in the radiative J/psi decays and some relatively weaker candidates from direct pattern recognition in hadronic spectroscopy, nonet + glueball ..-->.. decuplet with characteristic mixing splitting. The evidence for glueballs is discussed and speculation on what lies beyond for the physics of the 21st Century is given. 36 references. |
