Non-Canonical Perturbation Theory of Non-Linear Sigma Models

V. Aldaya, M. Calixto, F. F. López-Ruiz

Published 2010-07-16Version 1

We explore the O(N)-invariant Non-Linear Sigma Model (NLSM) in a different perturbative regime from the usual relativistic-free-field one, by using non-canonical basic commutation relations adapted to the underlying O(N) symmetry of the system, which also account for the non-trivial (non-flat) geometry and topology of the target manifold.
