Supersymmetric Baryogenesis in a Hybrid Inflation Model
Yoshihiro Gunji, Koji Ishiwata, Takahiro Yoshida
We study baryogenesis in a hybrid inflation model which is embedded to the minimal supersymmetric model with right-handed neutrinos. Inflation is induced by a linear combination of…
Subcritical regime of hybrid inflation with modular symmetry
Yoshihiro Gunji, Koji Ishiwata, Takahiro Yoshida
We consider a supergravity model that has the modular symmetry and discuss the interplay between the neutrino mixing and inflation. The model contains right-handed neutrinos…
Subcritical hybrid inflation in a generalized superconformal model
Yoshihiro Gunji, Koji Ishiwata
We study a generalized superconformal model that gives rise to a subcritical regime of -term hybrid inflation. Exhibiting the model both in a Jordan frame and in the Einstein fr…
Leptogenesis after superconformal subcritical hybrid inflation
Yoshihiro Gunji, Koji Ishiwata
We consider an extended version of superconformal subcritical hybrid inflation model by introducing three right-handed neutrinos that have the Majorana mass terms. In the model one…
