Description
We complete the renormalization program of (projectable) Horava gravity. We show that the theory is renormalizable in any space-time dimension, preserving scaling and gauge invariance of the counter-terms at any order in the loop expansion. Later, we focus on 2+1 dimensions, where we show that the renormalization group flow of the marginal couplings contains a UV fixed point leading to asymptotic freedom.
These two results together imply that 2+1 Horava gravity is a complete theory of Quantum Gravity with dynamical degrees of freedom. This theory can thus be used as a toy-model to study fundamental aspects of quantum gravity.
