Hiding Lorentz invariance violation with MOND

Authors: Sanders, R. H.;

Hiding Lorentz invariance violation with MOND

Abstract

Ho��ava gravity is a attempt to construct a renormalizable theory of gravity by breaking the Lorentz Invariance of the gravitational action at high energies. The underlying principle is that Lorentz Invariance is an approximate symmetry and its violation by gravitational phenomena is somehow hidden to present limits of observational precision. Here I point out that a simple modification of the low energy limit of Ho��ava gravity in its non-projectable form can effectively camouflage the presence of a preferred frame in regions where the Newtonian gravitational field gradient is higher than $cH_0$; this modification results in the phenomenology of MOND at lower accelerations.

5 pages, revised field equation, discussion added on potentials and dark energy, in press PRD
