We construct a general effective dynamics for diffeomorphisms of spacetime, in a fixed external metric.

Scale-dependent Planck mass and Higgs VEV from holography and functional renormalization

no code implementations14 Sep 2011 Daniel Litim, Roberto Percacci, Leslaw Rachwal

We compute the scale-dependence of the Planck mass and of the vacuum expectation value of the Higgs field using two very different renormalization group methods: a "holographic" procedure based on Einstein's equations in five dimensions with matter confined to a 3-brane, and a "functional" procedure in four dimensions based on a Wilsonian momentum cutoff.
