Journal ArticleDOI
Galileon as a local modification of gravity
TL;DR: In this article, the authors study the connection between self-acceleration and the presence of ghosts for a quite generic class of theories that modify gravity in the infrared, defined as those that at distances shorter than cosmological, reduce to a certain generalization of the Dvali-Gabadadze-Porrati (DGP) effective theory.
Journal ArticleDOI
Galilean Genesis: An Alternative to inflation
TL;DR: In this paper, a cosmological scenario is proposed, in which standard inflation is replaced by an expanding phase with a drastic violation of the Null Energy Condition (NEC): the model is based on the recently introduced Galileon theories, which allow NEC violating solutions without instabilities.
Journal ArticleDOI
Ghosts in massive gravity
TL;DR: In this paper, it was shown that at the Vainshtein radius the mass of the ghost is of order of the inverse radius, so that the theory cannot be trusted inside this region, not even at the classical level.
Journal ArticleDOI
Galilean Genesis: an alternative to inflation
TL;DR: In this article, a cosmological scenario is proposed, in which standard inflation is replaced by an expanding phase with a drastic violation of the Null Energy Condition (NEC): \dot H >> H^2.
Journal ArticleDOI
Energy"s and amplitudes" positivity
TL;DR: In this article, an effective field theory that allows for stable NEC-violating solutions with exactly luminal excitations only is presented, and it is shown that the theory obeys standard positivity as implied by dispersion relations.
