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…

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…
