Generalized Proca action for an Abelian vector field
read the original abstract
We revisit the most general theory for a massive vector field with derivative self-interactions, extending previous works on the subject to account for terms having trivial total derivative interactions for the longitudinal mode. In the flat spacetime (Minkowski) case, we obtain all the possible terms containing products of up to five first-order derivatives of the vector field, and provide a conjecture about higher-order terms. Rendering the metric dynamical, we covariantize the results and add all possible terms implying curvature.

Stable colored black holes with quartic self-interactions
Analytic proof that branch I of non-Abelian black holes with quartic interactions is linearly stable while branch II is unstable, based on the sign of the effective potential in even and odd perturbation sectors.
