TL;DR
This paper discusses anomaly cancellation in gauged WZW models, exploring conditions for independent gauging of sectors and relating certain Toda theories to these models.
Contribution
It provides a general analysis of anomaly cancellation conditions and highlights the potential for independent gauging in gauged WZW models, including Toda theories.
Findings
Anomaly cancellation conditions are derived for general gauged WZW actions.
Independent gauging of left and right sectors is possible in specific cases.
Toda theories can be interpreted as particular instances of gauged WZW models.
Abstract
Some remarks are made about free anomaly groups in gauged WZW models. Considering a quite general action, anomaly cancellation is analyzed. The possibility of gauging left and right sectors independently in some cases is remarked. In particular Toda theories can be seen as such a kind of models.
