Scalar graviton in the healthy extension of Hořava-Lifshitz theory
Rong-Gen Cai, Bin Hu, Hong-Bo Zhang
In this note we study the linear dynamics of scalar graviton in a de Sitter background in the infrared limit of the healthy extension of Hořava-Lifshitz gravity with the dynamical…

Dynamical Scalar Degree of Freedom in Horava-Lifshitz Gravity
Rong-Gen Cai, Bin Hu, Hong-Bo Zhang
We investigate the linear cosmological perturbations of Hořava-Lifshitz gravity in a FRW universe without any matter. Our results show that a new gauge invariant dynamical scalar m…
