Gravity and the Higgs boson mass
Carlo Branchina, Vincenzo Branchina, Filippo Contino +2
According to usual calculations in quantum field theory, both in flat and curved spacetime, the mass of a scalar particle is quadratically sensitive to the ultimate scale of…

Diffeomorphism invariance of the effective gravitational action
Carlo Branchina, Vincenzo Branchina, Filippo Contino +2
We investigate on the diffeomorphism invariance of the effective gravitational action, focusing in particular on the path integral measure. In the literature, two different measure…

On the RG flow of the Newton and cosmological constant
Carlo Branchina, Vincenzo Branchina, Filippo Contino +2
In this note we comment on the RG flow of the Newton and cosmological constants, also in view of some recent claims [1] that would rise some doubts on the validity of our recent wo…
