Gravitino Problem in Inflation Driven by Inflaton-Polonyi Kähler Coupling
Fuminori Hasegawa, Kazunori Nakayama, Takahiro Terada +1
We discuss the cosmological gravitino problem in inflation models in which the inflaton potential is constructed from Kähler potential rather than superpotential: a representative…

Gravitino Problem in Minimal Supergravity Inflation
Fuminori Hasegawa, Kyohei Mukaida, Kazunori Nakayama +2
We study non-thermal gravitino production in the minimal supergravity inflation. In this minimal model utilizing orthogonal nilpotent superfields, the particle spectrum includes on…
