violation in modular invariant flavor models
Tatsuo Kobayashi, Yusuke Shimizu, Kenta Takagi +3
We study the spontaneous violation through the stabilization of the modulus in modular invariant flavor models. The -invaraiant potentential has the minimum only at ${…
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…
lepton flavor model and modulus stabilization from modular symmetry
Tatsuo Kobayashi, Yusuke Shimizu, Kenta Takagi +2
We study the modulus stabilization in an model whose flavor symmetry is originated from the modular symmetry. We can stabilize the modulus so that the invar…
New lepton flavor model from modular symmetry
Tatsuo Kobayashi, Yusuke Shimizu, Kenta Takagi +2
We study a flavor model with symmetry which originates from modular group. In symmetry, subgroup can be anomalous, and then can be violated to .…
Modular invariant flavor model in SU(5) GUT
Tatsuo Kobayashi, Yusuke Shimizu, Kenta Takagi +2
We present a flavor model with the modular invariance in the framework of SU(5) GUT. The modular forms of weights and give the quark and lepton mass matrices wi…
On Experimental Confirmation of the Corrections to the Fermi's golden rule
Kenzo Ishikawa, Osamu Jinnouchi, Arisa Kubota +3
Standards calculations by the Fermi's Golden rule involve approximations. These approximations could lead to deviations from the predictions of the standard model as discussed in a…
