Parameterised post-Newtonian formalism for the effective field theory of dark energy via screened reconstructed Horndeski theories
Cyril Renevey, Joe Kennedy, Lucas Lombriser
We bring together two popular formalisms which generically parameterise deviations from General Relativity on astrophysical and cosmological scales, namely the parameterised post-N…
Positivity bounds on reconstructed Horndeski models
Joe Kennedy, Lucas Lombriser
Positivity bounds provide conditions that a consistent UV-completion exists for a quantum field theory. We examine their application to Horndeski gravity models reconstructed from…
Screening and degenerate kinetic self-acceleration from the nonlinear freedom of reconstructed Horndeski theories
Joe Kennedy, Lucas Lombriser, Andy Taylor
We have previously presented a reconstruction of Horndeski scalar-tensor theories from linear cosmological observables. It includes free nonlinear terms which can be added onto the…
Reconstructing Horndeski models from the effective field theory of dark energy
Joe Kennedy, Lucas Lombriser, Andy Taylor
Studying the effects of dark energy and modified gravity on cosmological scales has led to a great number of physical models being developed. The effective field theory (EFT) of co…
