A hybrid seesaw model and hierarchical neutrino flavor structures based on symmetry
Mayumi Aoki, Daiki Kaneko
We propose a hybrid seesaw model based on flavor symmetry, which generates a large hierarchical flavor structure. In our model, tree-level and one-loop seesaw mechanisms pr…

Probing CP violating Higgs sectors via the precision measurement of coupling constants
Mayumi Aoki, Katsuya Hashino, Daiki Kaneko +2
We study how effects of the CP violation can be observed indirectly by precision measurements of Higgs boson couplings at a future Higgs factory such as the international linear co…

Multicomponent Dark Matter in Radiative Seesaw Models
Mayumi Aoki, Daiki Kaneko, Jisuke Kubo
We discuss radiative seesaw models, in which an exact symmetry is imposed. Due to the exact symmetry, neutrino masses are generated at a two-loop…
