Modulus D-term Inflation
Kenji Kadota, Tatsuo Kobayashi, Ikumi Saga +1
We propose a new model of single-field D-term inflation in supergravity, where the inflation is driven by a single modulus field which transforms non-linearly under the U(1) gauge…

Constraints on small-field axion inflation
Tatsuo Kobayashi, Akane Oikawa, Naoya Omoto +2
We study general class of small-field axion inflations which are the mixture of polynomial and sinusoidal functions suggested by the natural and axion monodromy inflations. The axi…
