Regular multi-horizon Lee-Wick black holes
Nicolò Burzillà, Breno L. Giacchini, Tibério de Paula Netto +1
In this paper we carry out a detailed analysis of the static spherically symmetric solutions of a sixth-derivative Lee-Wick gravity model in the effective delta source approximatio…
On effective models of regular black holes inspired by higher-derivative and nonlocal gravity
Tibério de Paula Netto, Breno L. Giacchini, Nicolò Burzillà +1
In this work we study static spherically symmetric solutions of effective field equations related to local and nonlocal higher-derivative gravity models, based on their associated…
Regular black holes from higher-derivative effective delta sources
Breno L. Giacchini, Tibério de Paula Netto
Certain approaches to quantum gravity and classical modified gravity theories result in effective field equations in which the original source is substituted by an effective one. I…
Renormalizability of nonlocal quantum gravity coupled to matter
Gianluca Calcagni, Breno L. Giacchini, Leonardo Modesto +2
We extensively study the ultraviolet quantum properties of a nonlocal action for gravity nonminimally coupled to matter. The theory unifies matter and gravity in an action principl…
