Functional Renormalization Group Flow of Massive Gravity
arXiv:2003.09030 · doi:10.1140/epjc/s10052-020-7835-8
Abstract
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.
