Which is the best inflation model?
David H. Lyth
Reasonable-looking models of inflation are compared, taking into account the possibility that the curvature perturbation might originate from some "curvaton" field different from t…
Can the curvaton paradigm accommodate a low inflation scale?
David H. Lyth
The cosmological curvature perturbation may be generated when some `curvaton' field, different from the inflaton, oscillates in a background of unperturbed radiation. In its simple…
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 CDM isocurvature perturbation in the curvaton scenario
David H Lyth, David Wands
We discuss the residual isocurvature perturbations, fully-correlated with the curvature perturbation, that are automatic in the curvaton scenario if curvaton decay is sufficiently…
Conserved cosmological perturbations
David H Lyth, David Wands
A conserved cosmological perturbation is associated with each quantity whose local evolution is determined entirely by the local expansion of the Universe. It may be defined as 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…
