Journal ArticleDOI
Consistent Extension of Horava Gravity
TL;DR: A natural extension of Horava's model for quantum gravity is proposed, which endows the scalar graviton mode with a regular quadratic action and remains power-counting renormalizable at low energies.
Journal ArticleDOI
Higgs inflation: consistency and generalisations
TL;DR: In this paper, the self-consistency of inflation in the Standard Model was analyzed and the authors determined the domain of energies in which this model represents a valid effective field theory as a function of the background Higgs field.
Journal ArticleDOI
On the Extra Mode and Inconsistency of Horava Gravity
TL;DR: In this paper, the consistency of Horava's proposal for a theory of quantum gravity from the low-energy perspective is analyzed both in the original formulation of the theory and in the Stueckelberg picture.
Journal ArticleDOI
On the extra mode and inconsistency of Hořava gravity
TL;DR: In this article, the authors investigated the consistency of Hořava's proposal for a theory of quantum gravity from the low energy perspective and uncovered the additional scalar degree of freedom arising from the explicit breaking of the general covariance and study its properties.
Journal ArticleDOI
Models of non-relativistic quantum gravity: The Good, the bad and the healthy
TL;DR: In this article, the authors examine several consistency issues present in three non-relativistic gravity theories: Hořava's projectable theory, the healthy non-projectable extension, and a new extension related to ghost condensation.
