Kähler anomalies in supergravity and flux vacua
Abstract
We review the subject of Kähler anomalies in gauged supergravity, emphasizing that field equations are inconsistent when the Kähler potential is non-invariant under gauge transformations or when there are elementary Fayet-Iliopoulos couplings. The covariant Kähler anomalies involve tensors which are composite functions of the scalars as well as the gauge field strength and space-time curvature tensors. Models with gauged U(1) shift symmetries which descend from flux vacuum solutions of string theory have uncanceled triangle anomalies but are nevertheless consistent. Specific anomaly cancellation conditions for Fayet-Iliopoulos models will be discussed in a sequel to this paper.
