Description
Vectors with ghost-free derivative self-interactions have been shown to have interesting cosmological applications. They form a ghost-free extension of the Proca theory that has a Galileonic longitudinal mode and can be generated naturally via a Higgs mechanism. In this talk I will discuss recent results on the covariantisation of these models and their relation to general ghost-free scalar-tensor theories.
