Inelastic strong interactions at high energies. Final report, June 1, 1976-May 31, 1984
Work in Reggeon Field Theory is described. Multiparticle processes were studied. Cut RFT's were examined and convergence of perturbation expansions was considered. An RFT with an internal symmetry was also investigated. We made a study of model independent predictions for various high energy cross-sections, introducing the concept of sections. We examined the quantum mechanics of polynomial potentials as a model for quantum field theories. We determined various convergence properties of approximate calculational methods. Various aspects of GUT's were studied. The Higgs sector was examined and various symmetry breaking patterns were found using different representations for the Higgs. Bounds were put on parameters of the theory at finite temperature. Lattice gauge theories were studied. We looked at one exactly soluble one-dimensional model, and then began an extended investigation of Hamiltonian Lattice gauge theories. We studied the weak coupling behavior of global and local abelian lattice gauge theories in arbitrary dimensions, using various periodic trial functions and the WKB approximation. Supersymmetry and supergravity were investigated. We examine the compatibility of scale transformations in super space and the properties of scale invarient theories in ordinary spacetime. We discovered the largest possible local linear symmetry which is allowed given the structure of spacetime. We developed a systematic method for performing dimensional reduction on theories which admit abelian killing vectors. 68 references.
