I. Jack, D.R.T. Jones, N. Mohammedi
TL;DR
This paper investigates the ultraviolet behavior of noncommutative non-linear sigma-models in two dimensions, including both bosonic and supersymmetric versions, with considerations of Wess-Zumino-Witten terms.
Contribution
It provides a detailed analysis of the ultraviolet properties of noncommutative sigma-models, highlighting differences with commutative cases and exploring supersymmetric extensions.
Findings
Ultraviolet properties depend on the presence of supersymmetry.
Wess-Zumino-Witten terms influence the UV behavior.
Noncommutativity introduces novel features in the models' UV behavior.
Abstract
We discuss the ultra-violet properties of bosonic and supersymmetric noncommutative non-linear sigma-models in two dimensions, both with and without a Wess-Zumino-Witten term.
