On the Vilkovisky-DeWitt approach and renormalization group in effective quantum gravity
Breno L. Giacchini, Tibério de Paula Netto, Ilya L. Shapiro
The effective action in quantum general relativity is strongly dependent on the gauge-fixing and parametrization of the quantum metric. As a consequence, in the effective approach…
Primordial universe with the running cosmological constant
Jhonny A. Agudelo Ruiz, Tibério de Paula Netto, Júlio C. Fabris +1
Theoretically, the running of the cosmological constant in the IR region is not ruled out. On the other hand, from the QFT viewpoint, the energy released due to the variation of th…
Gauge invariance of the background average effective action
Peter M. Lavrov, Eduardo Antonio dos Reis, Tibério de Paula Netto +1
Using the background field method for the functional renormalization group approach in the case of a generic gauge theory, we study the background field symmetry and gauge dependen…
Form factors and decoupling of matter fields in four-dimensional gravity
Sebastián A. Franchino-Viñas, Tibério de Paula Netto, Ilya L. Shapiro +1
We extend previous calculations of the non-local form factors of semiclassical gravity in to include the Einstein-Hilbert term. The quantized fields are massive scalar, fermio…
