Curvaton Dynamics
Konstantinos Dimopoulos, George Lazarides, David Lyth +1
In contrast to the inflaton's case, the curvature perturbations due to the curvaton field depend strongly on the evolution of the curvaton before its decay. We study in detail the…
The Curvaton as a Pseudo-Nambu-Goldstone Boson
K. Dimopoulos, D. H. Lyth, A. Notari +1
The field responsible for the cosmological curvature perturbations generated during a stage of primordial inflation might be the ``curvaton'', a field different from the inflaton f…
The Peccei-Quinn Field as Curvaton
Konstantinos Dimopoulos, George Lazarides, David Lyth +1
A simple extension of the minimal supersymmetric standard model which naturally and simultaneously solves the strong CP and mu problems via a Peccei-Quinn and a continuous R symmet…
