Renormalization group effects for a rank degenerate Yukawa matrix and the fate of the massless neutrino

Nicholas J. Benoit, Takuya Morozumi, Yusuke Shimizu +2

The Type-I seesaw model is a common extension to the Standard Model that describes neutrino masses. The Type-I seesaw introduces heavy right-handed neutrinos with Majorana mass tha…

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 ${…

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…

flavor symmetric model in SUSY SU(5) GUT

Yu Muramatsu, Hideaki Okane, Yusuke Shimizu +1

We propose a model with flavor symmetry for leptons and quarks in the framework of supersymmetric SU(5) grand unified theory (GUT). The running masses of quarks and charged l…

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…
