1201.6037 (Konstantinos Dimopoulos et al.)

The hybrid curvaton    [PDF]

Konstantinos Dimopoulos, Kazunori Kohri, Tomohiro Matsuda
We study both oscillating and inflating curvaton scenarios when the curvaton mechanism is caused by a hybrid potential. The source of the curvature perturbation is the inhomogeneous phase transition that causes the modulation of the onset of the oscillation. For the supergravity-motivated curvaton there is a possibility of finding natural coincidence of the energy density that is needed to affect non-Gaussianity in the curvaton scenario.
