Title: On renormalizablilty of Horava gravity

Abstract:
Horava gravity was proposed in 2009 as a power counting (PC) renormalizable theory of gravity in 3+1 dimensions. Since then, many studies have shown that the theory is phenomenologically viable, but there has been little progress on proving the renormalizablity and consistency of the proposal beyond PC. In my talk I will party fill this gap and show that the theory is indeed renormalizable in its simplest form and seems to be asymptotically free in 2+1. I’ll describe the difficulties we need to face to get results in the realistic 3+1 case.
