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…
Modulus linking leptonic CP violation to baryon asymmetry in modular invariant flavor model
Hiroshi Okada, Yusuke Shimizu, Morimitsu Tanimoto +1
We propose an modular invariant flavor model of leptons, in which both CP and modular symmetries are broken spontaneously by the vacuum expectation value of the modulus .…
Lepton flavor model with modular symmetry in large volume limit
Takehiko Asaka, Yongtae Heo, Takahiro Yoshida
We consider the modular symmetry associated with the compactification of extra dimensions as the flavor symmetry on lepton sector. Especially, we propose a model based on the modul…
Modular invariance and leptogenesis
Takehiko Asaka, Yongtae Heo, Takuya H. Tatsuishi +1
We consider a model with three right-handed neutrinos in which Yukawa coupling constants and Majorana masses are obtained by requiring the modular symmetry. It has been shown…
Resonant leptogenesis at TeV-scale and neutrinoless double beta decay
Takehiko Asaka, Takahiro Yoshida
We investigate a resonant leptogenesis scenario by quasi-degenerate right-handed neutrinos which have TeV-scale masses. Especially, we consider the case when two right-handed neutr…
