Renormalization of the Non-Linear Sigma Model in Four Dimensions. A two-loop example
Ruggero Ferrari, Andrea Quadri
The renormalization procedure of the non-linear SU(2) sigma model in D=4 proposed in hep-th/0504023 and hep-th/0506220 is here tested in a truly non-trivial case where the non-line…

A Weak Power-Counting Theorem for the Renormalization of the Non-Linear Sigma Model in Four Dimensions
Ruggero Ferrari, Andrea Quadri
The formulation of the non-linear sigma model in terms of flat connection allows the construction of a perturbative solution of a local functional equation encoding the underlying…

Endowing the Nonlinear Sigma Model with a Flat Connection Structure: a Way to Renormalization
Ruggero Ferrari
We discuss the quantized theory of a pure-gauge non-abelian vector field (flat connection) as it would appear in a mass term a` la Stueckelberg. However the paper is limited to the…
