Insights into the highest natural scale: Finite naturalness challenges inflationary dynamics
Pier Giuseppe Catinari, Loris Del Grosso, Luca Di Giovanni +1
We apply the criterion of finite naturalness to the limiting case of a generic heavy sector decoupled from the Standard Model. The sole and unavoidable exception to this decoupling…

Is the formation of primordial black holes from single-field inflation compatible with standard cosmology?
Sasha Allegrini, Loris Del Grosso, Antonio J. Iovino +1
In this work, we investigate the generation of primordial black holes (PBHs) within the framework of single-field inflationary models and their compatibility with the cosmological…
