On IR solutions in Horava gravity theories

Abstract

In this note we search for large distance solutions of Horava gravity. In the case of the "detailed balance" action, gravity solutions asymptote to IR only above the cosmological constant (\simhorizon) scale. However, if one adds IR dominant terms αR(3)+βΛW\alpha R^{(3)}+\beta \Lambda_W, one can recover general relativity solutions on usual scales in the real Universe, provided one fine-tunes the cosmological constant, reobtaining the usual cosmological constant problem. We comment on pp wave solutions, in order to gain insight into the relativistic properties of the theory.
