Chiral gravitational waves from [formula omitted] Hořava–Lifshitz gravity

Abstract

We construct the chiral gravitational waves from the z = 2 Hořava–Lifshitz gravity with gravitational Chern–Simons term in the de Sitter and Minkowski backgrounds. These gravitational waves which show a feature of the Hořava–Lifshitz gravity may be related to the generalized uncertainty principle. In addition, we find the classical and quantum IR–UV transition rules in the z = 2 Hořava–Lifshitz gravity.
