(Non-)Abelian discrete anomalies
Published Web Locationhttps://doi.org/10.1016/j.nuclphysb.2008.07.005
We derive anomaly constraints for Abelian and non-Abelian discrete symmetries using the path integral approach. We survey anomalies of discrete symmetries in heterotic orbifolds and find a new relation between such anomalies and the so-called 'anomalous' U(1). © 2008 Elsevier B.V. All rights reserved.
