Exploring new corners of asymptotically safe unimodular quantum gravity
Gustavo P. de Brito, Antonio D. Pereira, Arthur F. Vieira
The renormalization group flow of unimodular quantum gravity is investigated within two different classes of truncations of the flowing effective action. In particular, we search f…
Unimodular quantum gravity: Steps beyond perturbation theory
Gustavo P. de Brito, Antonio D. Pereira
The renormalization group flow of unimodular quantum gravity is computed by taking into account the graviton and Faddeev-Popov ghosts anomalous dimensions. In this setting, a ultra…
Quantum corrected gravitational potential beyond monopole-monopole interactions
G. P. de Brito, M. G. Campos, L. P. R. Ospedal +1
We investigate spin- and velocity-dependent contributions to the gravitational inter-particle potential. The methodology adopted here is based on the expansion of the effective act…
Mass dimension one fermions at 1-loop
G. P. de Brito, J. M. Hoff da Silva, V. Nikoofard
We investigate 1-loop contributions to the 2- and 4-point correlation functions within a theory for fermions with mass dimension one with a simple quartic self-interaction term. Th…
A link that matters: Towards phenomenological tests of unimodular asymptotic safety
Gustavo P. de Brito, Astrid Eichhorn, Antonio D. Pereira
Constraining quantum gravity from observations is a challenge. We expand on the idea that the interplay of quantum gravity with matter could be key to meeting this challenge. Thus,…
On the impact of Majorana masses in gravity-matter systems
Gustavo P. de Brito, Yuta Hamada, Antonio D. Pereira +1
We investigate the Higgs-Yukawa system with Majorana masses of a fermion within asymptotically safe quantum gravity. Using the functional renormalization group method we derive the…
