Locally covariant chiral fermions and anomalies
arXiv:1407.1994 · doi:10.1016/j.nuclphysb.2014.11.008
Abstract
We define chiral fermions in the presence of non-trivial gravitational and gauge background fields in the framework of locally covariant field theory. This allows to straightforwardly compute the chiral anomalies on non-compact Lorentzian space-times, without recourse to a weak field approximation.
