This project continues work on a variety of topics in                      electroweak interaction physics and theory and phenomenology of                 CP violations, with emphasis on stimulating new experimental                    analyses.  It also includes work on dynamical models of the                     quark mass matrix within a given generation, as a first step                    investigating various aspects of the strong-coupling standard                   model, such as the effect of radiative corrections.  An                         extensive theoretical analysis of various hypernuclear                          transitions, now underway, will be compared with data on the A-                 dependence of these processes.                                                       A program on studies of the strong interactions will                       continue.  An improved derivation of the effective Lagrangian                   starting from the basic QCD theory of quarks and gluons is                      being attempted.  Other studies involving the so-called                         anomalous sector of the theory, and an effort to present a                      unified phenomenology of all low energy processes are planned.                  An attempt to compute bag mode amplitudes to higher order                       in the QCD coupling constant via a mode-truncation approach has                 begun.                                                                               Theoretical work in other areas will continue.  A                          calculation to determine the effects on the gravitational field                 due to the presence of matter at nonzero temperature is nearing                 completion, and future work will apply this procedure to the                    early universe.  A model of quark matter in a diquark phase is                  under investigation.  Research continues on the solar neutrino                  problem.  Recent work on the source of baryon-number violating                  interactions motivates a re-examination of past studies of                      baryogenesis.
