The complete one-loop regularization of a two-dimensional generalized sigma model is performed by means of the Schwinger proper-time method. The result for the beta functions is in agreement with the previous computations. The explicit expression of the wave-function regularization, required to make the theory finite off shell, is also obtained.

Abstract
The complete one-loop regularization of a two-dimensional generalized sigma model is performed by means of the Schwinger proper-time method. The result for the beta functions is in agreement with the previous computations. The explicit expression of the wave-function regularization, required to make the theory finite off shell, is also obtained.File in questo prodotto:
