The model that predicts the maximal 2-3 mixing and CP violation for neutrinos is revisited
Eiichi Takasugi
The model of the neutrino mass matrix which we proposed in 2000 is revisited in the light of the recent T2K experiments. This model has the special property that it predicts the ma…
Effects on sinθ_{12} from perturbation of the neutrino mixing matrix with the partially degenerated neutrino masses
Takeshi Araki, Eiichi Takasugi
We consider a situation where the leading-order neutrino mass matrix is derived by a theoretical ansatz and reproduces the experimental data well, but not completely. Then, the nex…
Froggatt-Nielsen hierarchy and the neutrino mass matrix
Hiroshi Kamikado, Tetsuo Shindou, Eiichi Takasugi
We study the neutrino mass matrix derived from the seesaw mechanism in which the neutrino Yukawa couplings and the heavy Majorana neutrino mass matrix are controlled by the Froggat…
Neutrino Mixing based on Mass Matrices with a Symmetry
Yoshio Koide, Eiichi Takasugi
Under the assumption that the symmetry is broken only through phases, we give a systematical investigation of possible lepton mass matrix forms without referri…
CP violation due to multi Froggatt-Nielsen fields
Shinya Kanemura, Koichi Matsuda, Toshihiko Ota +4
We study how to incorporate CP violation in the Froggatt--Nielsen (FN) mechanism. To this end, we introduce non-renormalizable interactions with a flavor democratic structure to th…
Colour entangled orphan quarks and dark energy from cosmic QCD phase transition
Shibaji Banerjee, Abhijit Bhattacharyya, Sanjay K. Ghosh +5
The present day astrophysical observations indicate that the universe is composed of a large amount of dark energy (DE) responsible for an accelerated expansion of the universe, al…
