Mimetic covariant renormalizable gravity

19 Nov 2015 Myrzakulov Ratbay Sebastiani Lorenzo Vagnozzi Sunny Zerbini Sergio

Covariant renormalizable gravity is a Horava-like extension of general relativity, enjoying full diffeomorphism invariance. However, the price to pay in order to maintain both covariance and renormalizability is the presence of an unknown fluid, whose non-standard coupling dynamically breaks Lorentz invariance...
