Chiral gravitational waves from z=2 Horava-Lifshitz gravity

We construct the chiral gravitational waves from the z = 2 Horava-Lifshitz gravity with gravitational Chern-Simons term in the de Sitter and Minkowski backgrounds. These gravitational waves which show a feature of the Horava-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 Horava-Lifshitz gravity. (C) 2010 Elsevier B.V. All rights reserved.
