Horndeski: beyond, or not beyond?
Marco Crisostomi, Matthew Hull, Kazuya Koyama +1
Determining the most general, consistent scalar tensor theory of gravity is important for building models of inflation and dark energy. In this work we investigate the number of de…
Covariantised Vector Galileons
Matthew Hull, Kazuya Koyama, Gianmassimo Tasinato
Vector Galileons are ghost-free systems containing higher derivative interactions of vector fields. They break the vector gauge symmetry, and the dynamics of the longitudinal vecto…
A Higgs Mechanism for Vector Galileons
Matthew Hull, Kazuya Koyama, Gianmassimo Tasinato
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…
