Vacuum stability in Geometric Trinity of Gravity
Vincenzo Branchina, Salvatore Capozziello, Filippo Contino +1
The decay of a metastable (false) vacuum plays a crucial role in constraining Standard Model and beyond the Standard Model physics. In particular, it has been shown that gravity ca…
Primary Constraints of Newer General Relativity
Carmen Ferrara, Alexey Golovnev, María José Guzmán
We study the primary constraint structure of Newer General Relativity, a gravity theory based on a torsionless teleparallel geometry. The gravitational action is built from a scala…
Extended Geometric Trinity of Gravity
Salvatore Capozziello, Sara Cesare, Carmen Ferrara
Extensions of equivalent representations of gravity are discussed in the metric-affine framework. First, we focus on: (i) General Relativity, based upon the metric tensor whose dyn…
The Equivalence Principle as a Noether Symmetry
Salvatore Capozziello, Carmen Ferrara
The Equivalence Principle is considered in the framework of metric-affine gravity. We show that it naturally emerges as a Noether symmetry starting from a general non-metric theory…
The role of the boundary term in symmetric teleparallel gravity
Salvatore Capozziello, Vittorio De Falco, Carmen Ferrara
In the framework of metric-affine gravity, we consider the role of the boundary term in Symmetric Teleparallel Gravity assuming models where is a smooth function of th…
