Reheating processes after Starobinsky inflation in old-minimal supergravity
Takahiro Terada, Yuki Watanabe, Yusuke Yamada +1
We study reheating processes and its cosmological consequences in the Starobinsky model embedded in the old-minimal supergravity. First, we consider minimal coupling between the gr…
Generic Scalar Potentials for Inflation in Supergravity with a Single Chiral Superfield
Sergei V. Ketov, Takahiro Terada
We propose a large class of supergravity models in terms of a single chiral matter superfield, leading to (almost) arbitrary single-field inflationary scalar potentials similar to…
Inflation in Supergravity with a Single Chiral Superfield
Sergei V. Ketov, Takahiro Terada
We propose new supergravity models describing chaotic Linde- and Starobinsky-like inflation in terms of a single chiral superfield. The key ideas to obtain a positive vacuum energy…
Complexified Starobinsky Inflation in Supergravity in the Light of Recent BICEP2 Result
Koichi Hamaguchi, Takeo Moroi, Takahiro Terada
Motivated by the recent observation of the B-mode signal in the cosmic microwave background by BICEP2, we stuty the Starobinsky-type inflation model in the framework of old-minimal…
