Quantum fluctuations of pseudoparticles in the nonlinear sigma-model. [Schroedinger equation]

Description: An investigation is presented of quantum fluctuations about pseudoparticle solutions in the two-dimensional sigma-model. First, for the one pseudoparticle case, one solves the small oscillation problem and compute the first quantum correction to the classical result. In the two-pseudoparticle case, one transforms the small oscillation problem into an ordinary Schrodinger equation with an interaction depending on distance between the pseudoparticles. One can then solve the limiting cases of zero… more

Path integral quantization of solitons

Description: A review of some recent work on the collective coordinate approach to perturbation expansion about soliton solutions is presented. Consistent formulation of the method in framework of the Feynman path integral quantization procedure is described. As an illustrative application one discusses in detail a perturbation expansion for scattering of solitons.

Field Theories in Terms of Particle-String Variables: Spin, Internal Symmetries and Arbitrary Dimension

Description: Essential tools are provided for a program of rewriting field theories in terms of particle-string variables. The general methods are illustrated in the case of quantum chromodynamics: (1) One finds the particle-trajectoy representation for the quark Green's functional. (2) One derives directly correct end-point terms for quarks at the ends of strings. (1) and (2) are for any number of dimensions. (3) In two dimensions, one finds a functional bridge from quantum chromodynamics to the Bardeen-Ba… more

Progress report of a research program in experimental and theoretical high energy physics, 1 January 1992--31 May 1992

Description: This report discusses research at Brown University in experimental and theoretical high energy physics. Some of the research programs conducted are: interactions of leptons and hadrons form accelerator and astrophysical sources; hadron interactions with hydrogen and heavier nuclei; large volume detector at the Gran Sasso Laboratory; GEM collaboration at SSC; and hadron colliders and neutrino physics.
