abstract
We perform the Batalin-Fradkin-Vilkovisky quantization of the anisotropic conformal Horava theory in d spatial dimensions. We introduce a model with a conformal potential suitable for any dimension. We define an anisotropic and local gauge-fixing condition that accounts for the spatial diffeomorphisms and the anisotropic Weyl transformations. We show that the BRST transformations can be expressed mainly in terms of a spatial diffeomorphism along a ghost field plus a conformal transformation with another ghost field as argument. We study the quantum Lagrangian in the d=2 case, obtaining that all propagators are regular, except for the fields associated with the measure of the second-class constraints. This behavior is qualitatively equal to the nonconformal case.

A Lapse in the Cosmological Constant Problem with Bulk Dynamics
Constant shifts of the local matter vacuum energy cancel from the semiclassical background Einstein equations in a compact 5D foliation, while finite winding Casimir energies remain and must be suppressed by the bulk spectrum.
