Work is reported in the area of implementing QCD with dynamical fermions on a lattice parallel processor. Work on lattice gauge theory is reported, particularly the construction and use of high speed parallel computers for the Monte Carlo simulation of lattice quantum chromodynamics. Other work includes research on the long-range forces that arise from multi-photon exchange between diverse systems, and particle-antiparticle oscillations. Also reported is work on composite-Higgs models, composite fermion models, calculating corrections propagators in near-constant background fields, and calculating gluon scattering amplitudes using techniques derived from string theory. Soliton stars, black holes, and Hawking radiation were studied. An analytic expression was found for an inclusive two minijet cross section at collider energies in QCD. The very early stage of an ultra-relativistic heavy ion collision was studied. Research on glueball masses in QCD, the first Chern number of the normal bundle of work surface of a string, and computation of the rate of baryogenesis via processes involving homotopically nontrivial paths on configuration space is also reported. Problems arising from the application of high energy physics to the study of cosmology are also studied. (LEW)
