Global gauge anomalies in coset models of conformal field theory

arXiv:1301.2517 · doi:10.1007/s00220-014-1995-z

Abstract

We study the occurrence of global gauge anomalies in the coset models of two-dimensional conformal field theory that are based on gauged WZW models. A complete classification of the non-anomalous theories for a wide family of gauged rigid adjoint or twisted-adjoint symmetries of WZW models is achieved with the help of Dynkin's classification of Lie subalgebras of simple Lie algebras.
