Unification of the soluble two-dimensional vector coupling models
- Department of Physics and Astronomy, University of Rochester, Rochester, New York 14627 (United States)
The general theory of a massless fermion coupled to a massive vector meson in two dimensions is formulated and solved to obtain the complete set of Green{close_quote}s functions. Both vector and axial-vector couplings are included. In addition to the boson mass and the two coupling constants, a coefficient which denotes a particular current definition is required for a unique specification of the model. The resulting four-parameter theory and its solution are shown to reduce in appropriate limits to all the known soluble models, including in particular the Schwinger model and its axial-vector variant. {copyright} {ital 1997} {ital The American Physical Society}
