Decay amplitudes in two-dimensional QCD
Abstract
Description
Decay amplitudes for mesons in two-dimensional QCD are discussed. We show that in spite of an infinite number of conserved charges, particle production is not entirely suppressed. This phenomenon is explained in terms of quantum corrections to the combined algebra of higher-conserved and spectrum-generating currents. We predict the qualitative form of particle production probabilities and verify that they are in agreement with numerical data. We also discuss four-dimensional self-dual Yang-Mills theory in the light of our results.
We discuss in more detail the background material and elaborate on the consequences of the new results. New equations and text are added and the figures are efficiently regenerated by a fortran program, latex file, 13 pages, 4 figures in encapsulated postscript files, uses epsf. minor changes, version to appear in Physical Review D
