Anomalous coupling of scalars to gauge fields
journal contribution
posted on 2023-06-07, 22:44 authored by Philippe Brax, Clare Burrage, Anne-Christine Davis, David SeeryDavid Seery, Amanda WeltmanWe study the transformation properties of a scalar-tensor theory, coupled to fermions, under the Weyl rescaling associated with a transition from the Jordan to the Einstein frame. We give a simple derivation of the corresponding modification to the gauge couplings. After changing frame, this gives rise to a direct coupling between the scalar and the gauge fields.
