ACT stands for Awkward Cosmology Theories
Loris Del Grosso, Alfredo Urbano, Marcello Ziccolella
Recent Atacama Cosmology Telescope (ACT) observations, combined with Planck, favor a scalar spectral index in tension with Starobinsky inflation. Two main strategies have been prop…
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…
Compact objects in and beyond the Standard Model from non-perturbative vacuum scalarization
Loris Del Grosso, Paolo Pani, Alfredo Urbano
We consider a theory in which a real scalar field is Yukawa-coupled to a fermion and has a potential with two non-degenerate vacua. If the coupling is sufficiently strong, a collec…
