Dirac-Gleichung , Yang-Mills-Theorie , Theorie der Sachzwänge
Abstract:
The structure of the constraint set in the Yang-Mills-Dirac theory in a contractible bounded domain is analysed under the bag boudary conditions. The gauge symmetry group is identified, and it is proved that its action on the phase space is proper and admits slices. The reduced phase space is shown to be the union of symplectic manifolds, each of which corresponds to a definite mode of symmetry breaking.
