Integrability and Definition of Current in the Thirring Model

概要
- 論文の詳細を見る
The canonical interaction Hamiltonian in the Thirring model does not satisfy the integrability condition. Then, first of all the integrable Hamiltonian is obtained, which involves one and only one parameter β, the coupling constant in the correctly quantized version. The quantities such as the current and the propagator are uniquely written in terms of β. An ambiguity, however, exists in the relation of βand the coupling constant λin the classical Lagrangian. This ambiguity is merely apparent and is the one often taken up by several authors in connection with the definition of the current. It is explained why Feynman rules are free from such an ambiguity. The massive vector-meson model is also investigated.
