Curvaton paradigm can accommodate multiple low inflation scales
Tomohiro Matsuda
Recent arguments show that some curvaton field may generate the cosmological curvature perturbation. As the curvaton is independent of the inflaton field, there is a hope that the…
Q ball inflation
Tomohiro Matsuda
We show that inflation can occur in the core of a Q-ball.
Comment on the stability of the Yukawa couplings and the cosmological problems of intersecting brane models
Tomohiro Matsuda
In string theory, stabilization of moduli fields and their cosmological implications have been discussed by many authors. In this paper we do not consider conventional modulus, nor…
Incidental brane defects
Tomohiro Matsuda
In the models of brane construction, the isometry of a compactified space might be broken by branes. In four-dimensional effective Lagrangian, the breaking of the isometry is seen…
Hybridized Affleck-Dine baryogenesis
Tomohiro Matsuda
We propose a novel scenario for Affleck-Dine baryogenesis in the braneworld, considering the hybrid potential for the Affleck-Dine field. Destabilization of the flat direction is n…
Non-tachyonic brane inflation
Tomohiro Matsuda
We consider non-tachyonic hybrid inflation in the context of the braneworld cosmology. When one considers models for brane inflation, hybrid inflation is a natural consequence of t…
