A Higgs mechanism for vector Galileons
Research output: Contribution to journal › Article › peer-review
Vector theories with non-linear derivative self-interactions that break gauge
symmetries have been shown to have interesting cosmological applications. In this paper we
introduce a way to spontaneously break the gauge symmetry and construct these theories
via a Higgs mechanism. In addition to the purely gauge field interactions, our method
generates new ghost-free scalar-vector interactions between the Higgs field and the gauge
boson. We show how these additional terms are found to reduce, in a suitable decoupling
limit, to scalar bi-Galileon interactions between the Higgs field and Goldstone bosons. Our
formalism is first developed in the context of abelian symmetry, which allows us to connect
with earlier work on the extension of the Proca action. We then show how this formalism
is straightforwardly generalised to generate theories with non-abelian symmetry.
