Dynamical generation of quark/lepton mass hierarchy in an extra dimension
Yukihiro Fujimoto, Kouhei Hasegawa, Kenji Nishiwaki +4
We show that the observed quark/lepton mass hierarchy can be realized dynamically on an interval extra dimension with point interactions. In our model, the positions of the point i…
Comprehensive Analysis of Yukawa Hierarchies on with Magnetic Fluxes
Yukihiro Fujimoto, Tatsuo Kobayashi, Kenji Nishiwaki +2
Based on the result of classification in our previous work, we exhaustively investigate Yukawa sector of model on magnetized orbifolds , , $T^{2}/Z…
Active Dirac Neutrinos via Doublets in 5d
Yukihiro Fujimoto, K. Hasegawa, Tomoaki Nagasawa +3
We propose a new mechanism to generate minuscule active neutrino masses in a five-dimensional~(5d) spacetime of an interval without introducing singlet neutrinos. Under a…
Classification of three-generation models on magnetized orbifolds
Tomo-hiro Abe, Yukihiro Fujimoto, Tatsuo Kobayashi +4
We classify the combinations of parameters which lead three generations of quarks and leptons in the framework of magnetized twisted orbifolds on , , an…
Realization of the Lepton Flavor Structure from Point Interactions
Yukihiro Fujimoto, Kenji Nishiwaki, Makoto Sakamoto +1
We investigate a 5d gauge theory on with point interactions. The point interactions describe extra boundary conditions and provide three generations, the charged lepton mass…
Realization of lepton masses and mixing angles from point interactions in an extra dimension
Yukihiro Fujimoto, Kenji Nishiwaki, Makoto Sakamoto +1
We investigate a model on an extra dimension where plenty of effective boundary points described by point interactions (zero-thickness branes) are arranged. After suitably se…
