DESCRIPTION:Tuesday\, March 25\, 2-3\:30pm\; Presenter\:  Terry Goldma
 n (LANL)\; Room 190\, Physics & Astronomy. \n\n\n\nNuclear physics has
  been built on the fact that nuclei are well described as bound states
  of nucleons that are almost identical to the free proton and neutron.
  However\, these baryons are known to be composites of quarks with ext
 remely strong Quantum ChromoDynamic (QCD) interactions. Why are the nu
 cleons in nuclei not significantly distorted from their free space str
 ucture? We show that the two principle features of QCD phenomenology a
 ccount for this qualitatively and demonstrate it quantitatively by con
 structing two small \nnuclei directly in terms of quarks. Predictions 
 from this model for the "EMC effect" in deep inelastic scattering of l
 eptons on nuclei appear to be accurate. A dibaryon that does not have 
 nuclear characteristics is also predicted\, for which there is "almost
 " evidence. We conclude that the nucleon-nucleon potential and meson-e
 xchange approaches to nuclear physics bear similarities to chemistry b
 efore the appreciation of the electronic structure of atoms\, and that
  body-fixed models of nuclear structure in terms of quark exchanges ma
 y lead to deeper understanding in a fashion parallel to that whereby c
 hemistry advanced beyond such concepts as electron affinity\, electron
 egativity\, etc.
