Orthonormal spin-flavor wave functions of Lorentz covariant quark models of the Bakamjian-Thomas type are constructed for nucleon resonances. Three different bases are presented. The manifestly Lorentz covariant Dirac-Melosh basis is related to the Pauli-Melosh basis and the symmetrized Bargmann-Wigner basis that are manifestly orthogonal.

Elements of a new model of strong interactions are described. The model is based on an extension of electrodynamics that is derived from a regular Lagrangian density. Here the electric and magnetic fields of Maxwell equations play a symmetric role. It is shown that results are in accordance with general properties of nuclear and nucleon systems.

Nuclear Physics is the branch of physics that deals with the properties and structure of matter on the hadronic level. In this article we review briefly the history of this field, which has a major role in the development of our understanding of nature. We then proceed to give an outline of a current perspective of the field and of some of the issues that are now on its frontiers.

Bertsch Dept. of Physics and Institute for Nuclear Theory, FM-15 University of Washington Seattle, WA 98195 Abstract The interferometric analysis of meson correlations provides a measure of the average phase space density of the mesons in the final state. This quantity is a useful indicator of ...
