Motivated by the fact that the non-cancellation of infrared divergences in QCD can be avoided by using soft degenerate states or coherent states in the initial state, it is proposed that the partons be identified with nearly degenerate, coherent quark-gluon ''jet'' states. An investigation is discussed of whether a ''jet'' based factorization, which occurs at higher twist, is a natural property of QCD and whether it maintains the universality of mass singularities and the factorization of QCD processes ito short-distance and long-distance parts. The coherent state operator exponentiation theorem is used to incorporate spectator interactions in order to develop a Hamiltonian approach to analyze rearrangement effects in hadronic collisions. The relationships among this operator exponentiation, the higher twist ''quasi-partonic operators,'' and the non-abelian eikonal-exponentiation theorem are being examined. Using methods developed for QCD, exploratory investigations are being made of the infrared structure of some supersymmetric and superstring theories. In a second program, because of the successul applications of the phi phi symmetry test by the Mark III collaboration, fundamental tests are being devised which can be used to probe discrete symmetries, and their possible violations, in the required ''new physics'' beyond the standard model. Using the helicity formulation for three-body decays, the sequential decay H ..-->.. anti f/sub 1/f/sub 2/ are analyzed where anti f/sub 1/f/sub 2/ are an antilepton-lepton pair or an antiquaark-quark pair. 47 refs.
