On the structure of interactions of mass dimension one fermions: a functional renormalization group perspective

Gustavo P. de Brito

In this paper, we provide the first systematic investigation of renormalization group properties of mass dimension one fermions described by ELKO spinors. By construction, ELKOs mu…

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…

Light fermions in color: why the quark mass is not the Planck mass

Gustavo P. de Brito, Astrid Eichhorn, Shouryya Ray

We investigate whether quantum gravity fluctuations can break chiral symmetry for fermions that are charged under a and an gauge symmetry and thus closely r…

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…
