The running vacuum in effective quantum gravity
Breno L. Giacchini, Tibério de Paula Netto, Ilya L. Shapiro
We briefly review the previous works on the renormalization group in quantum general relativity with the cosmological constant, based on the Vilkovisky and DeWitt version of effect…
Effective quantum gravity, cosmological constant and the Standard Model of particle physics
Breno L. Giacchini, Tibério de Paula Netto, Ilya L. Shapiro
The renormalization group in effective quantum gravity can be consistently formulated using the Vilkovisky and DeWitt version of effective action and assuming a non-zero cosmologic…
Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
Action principle selection of regular black holes
Breno L. Giacchini, Tibério de Paula Netto, Leonardo Modesto
We elaborate on the role of higher-derivative curvature invariants as a quantum selection mechanism of regular spacetimes in the framework of the Lorentzian path integral approach…
