Gauge dependence of momentum running in higher-derivative gravity
Diego Buccio, Gustavo P. De Brito, Luca Parente
Recent works have argued that improved one-loop beta-functions capturing the physical momentum dependence of one-loop corrected higher-derivative gravity theories are the most suit…
Yukawa interactions in Quantum Gravity
Gustavo P. de Brito, Manuel Reichert, Marc Schiffer
We present the first complete next-to-leading-order analysis of a Yukawa system within the framework of asymptotically safe quantum gravity. Our results are obtained through a syst…
Quark Propagator at one-loop in the Refined Gribov-Zwanziger framework
Gustavo P. de Brito, Philipe De Fabritiis, Antonio D. Pereira
The Refined Gribov-Zwanziger scenario is a local and renormalizable setup in which infinitesimal Gribov copies are eliminated and further non-perturbative effects are accounted for…
Neutrino mass generation in asymptotically safe gravity
Gustavo P. de Brito, Astrid Eichhorn, Antonio D. Pereira +1
There exist several distinct phenomenological models to generate neutrino masses. We explore, which of these models can consistently be embedded in a quantum theory of gravity and…
