Quantum effective action for degenerate vector field theories
Michael S. Ruf, Christian F. Steinwachs
We calculate the divergent part of the one-loop effective action in curved spacetime for a particular class of second-order vector field operators with a degenerate principal part.…

Renormalization of generalized vector field models in curved spacetime
Michael S. Ruf, Christian F. Steinwachs
We calculate the one-loop divergences for different vector field models in curved spacetime. We introduce a classification scheme based on their degeneracy structure, which encompa…
