A New Type of Complex Neutrino Mass Texture and mu-tau Symmetry
Ichiro Aizawa, Masaki Yasue
Relying upon the usefulness of the μ-τsymmetry, we find a new type of neutrino mass texture with a single phase parameter δthat describes maximal atmospheric neutrino mixing and Di…
Determination of Neutrino Mass Texture for Maximal CP Violation
Ichiro Aizawa, Teruyuki Kitabayashi, Masaki Yasue
We show a general form of neutrino mass matrix (M), whose matrix elements are denoted by M_{ij} (i.j=e, mu, tau) as flavor neutrino masses, that induces maximal CP violation as wel…
μ-τSymmetry and Maximal CP Violation
Teruyuki Kitabayashi, Masaki Yasue
We argue the possibility that a real part of a flavor neutrino mass matrix only respects a mu-tau symmetry. This possibility is shown to be extended to more general case with a pha…
Neutrino Mass Textures with Maximal CP Violation
Ichiro Aizawa, Teruyuki Kitabayashi, Masaki Yasue
We have found three types of neutrino mass textures, which give maximal CP-violation as well as maximal atmospheric neutrino mixing. These textures are described by six real mass p…
Constraints on Flavor Neutrino Masses and sin^2(2theta_{12})>>sin^2(theta_{13}) in Neutrino Oscillations
Ichiro Aizawa, Teruyuki Kitabayashi, Masaki Yasue
To realize the condition of sin^2(2theta_{12})>>sin^2(theta_{13}), we find constraints on flavor neutrino masses M_{ij} (ij=e,μ,τ): C1) c_{23}^2 M_{μμ} + s_{23}^2 M_{ττ} \approx 2…
