Renormalization Group Flow of Asymptotically Safe Gravity with Scalar Fields — •Peter Schuh — TU Dortmund, Deutschland

The Asymptotic Safety Scenario attempts to find a consistent model for gravity as a quantum field theory by proposing a fixed point in the renormalization group flow as a generalization of the concept of perturbative renormalizability. In this talk, the influence of multiple scalar particles on the existence and stability of fixed points is investigated, allowing for mass and interaction terms extending previous calculations.
