Particle production and dissipation caused by the Kaluza-Klein tower
Tomohiro Matsuda
Two-step dissipation is studied in supersymmetric models in which the field in motion couples to bulk fields in the higher dimensional space. Since the Kaluza-Klein tower of the in…
Primordial Black Holes from the inflating curvaton
Kazunori Kohri, Chia-Min Lin, Tomohiro Matsuda
The primordial black hole (PBH) formation is studied in light of the inflating curvaton. The typical scale of the PBH formation is determined by curvaton inflation, which may gener…
Non-Gaussianity in the inflating curvaton
Seishi Enomoto, Kazunori Kohri, Tomohiro Matsuda
Inflating curvaton can create curvature perturbation when the curvaton density is slowly varying. Using the delta-N formalism, we discuss the evolution of the curvature perturbatio…
Free light fields can change the predictions of hybrid inflation
Tomohiro Matsuda
We show that the free light scalar fields that may exist in the inflationary Universe can change the predictions of the hybrid inflation model. Possible signatures are discussed, w…
The hybrid curvaton
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 inhomogeneou…
