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…
Inflation in supergravity without Kahler potential
Shuntaro Aoki, Yusuke Yamada
We propose a new class of inflation models in supergravity with higher derivative terms. In those models, the Kähler potential does not contain the inflaton multiplet, but a supers…
Illustrating SUSY breaking effects on various inflation mechanisms
Hiroyuki Abe, Shuntaro Aoki, Fuminori Hasegawa +1
We consider the supersymmetry breaking effects on typical inflation models with different types of Kähler potential. The critical size of supersymmetry-breaking scale, above which…
Natural realization of large extra dimension in 5D supersymmetric theory
Yutaka Sakamura, Yusuke Yamada
An exponentially large extra dimension can be naturally realized by the Casimir energy and the gaugino condensation in 5D supersymmetric theory. The model does not require any hier…
