Infrared Screening of the Cosmological Constant
Vincenzo Branchina, Riccardo Gandolfo, Arcangelo Pernace
The observed cosmological constant is set by the deepest infrared scale of the present universe rather than by the microscopic scales that contribute to the vacuum energy. We show…
Quantum gravity and spectral running cutoff
Carlo Branchina, Vincenzo Branchina, Filippo Contino +2
We have recently shown that a natural way to implement the Wilsonian paradigm in gauge theories is through the introduction of a ``spectral cutoff", a cut on the eigenvalues of the…
Hard cutoff and gauge theories
V. Branchina, F. Contino, R. Gandolfo +1
According to usual calculations, the use of a hard cutoff in gauge theories leads to a violation of gauge invariance. This seems to generate a tension between gauge theories an…
