ALP inflation and Big Bang on Earth
Abstract We study a hilltop inflation model where an axion-like particle (ALP) plays the role of the inflaton. We find that, for a broad class of potentials, the decay constant and the mass at the potential minimum satisfy the relation, m ϕ ∼ 10− 6 f, to explain the CMB normalization. The ALP is ne...
