Quantization with a global constraint and IR finiteness of two-dimensional Goldstone systems
Description
A method of quantizing Goldstone systems with a global continuous symmetry by introducing a global constraint is presented. This procedure is used to study the IR finiteness of the weak coupling expansion of such models at two dimensions. In this scheme, the propagator is IR finite at any dimension and all observables are proved to be IR finite at d = 2. The IR properties of non-standard models are elucidated. (orig.)
