Description
Horava Gravity is a field-theoretic model that shares many properties of GR. Namely it has metric as a basic degree of freedom and possesses spatial diffeomorphisms, as well as global time reparameterizations, as its symmetries. The feature of the model is the potentially much improved high energy behavior at the expense of forbidding the symmetry of local time reparameterizations and consequently Lorentz boosts. Heavily constrained as a phenomenological model, -- due to the constraints on Lorentz Violation, -- as a theoretical model it can provide a framework for asking questions in gravity-like theories that require access to the high energy regime. In the talk, I will report on the progress made on the understanding of its high energy properties, using QFT methods and tools.
