Maximiliano Binder: Functional Renormalization Group Flow of Massive Gravity

We apply the functional renormalization group equation to a massive Fierz–Pauli action in curved space and find that, even though a massive term is a modification in the infrared sector, the mass term modifies the value of the non-gaussian fixed point in the UV sector. We obtained the beta function for the scale dependent mass parameter and found that the massive Fierz–Pauli case still seems to be an asymptotically safe theory.
