A unifying description of dark energy
Jérôme Gleyzes, David Langlois, Filippo Vernizzi
We review and extend a novel approach that we introduced recently, to describe general dark energy or scalar-tensor models. Our approach relies on an ADM formulation based on the h…
Healthy theories beyond Horndeski
Jérôme Gleyzes, David Langlois, Federico Piazza +1
We introduce a new class of scalar-tensor theories that extend Horndeski, or "generalized galileon", models. Despite possessing equations of motion of higher order in derivatives,…
Essential Building Blocks of Dark Energy
Jerome Gleyzes, David Langlois, Federico Piazza +1
We propose a minimal description of single field dark energy/modified gravity within the effective field theory formalism for cosmological perturbations, which encompasses most exi…
