Three-loop singularity structure for a non-linear sigma model
P. V. Akacevich, A. V. Ivanov, I. V. Korenev
The paper is devoted to the three-loop renormalization of the effective action for a two-dimensional non-linear sigma model using the background field method and a cutoff regulariz…

On Two-Loop Effective Action of 2D Sigma Model
P. V. Akacevich, A. V. Ivanov
In this paper, we study two-loop contribution to the effective action of a two-dimensional sigma model. We derive a new formula, which can be applicable to a regularization of gene…
