Universality of Quark-Lepton Mass Matrix
The recently observed lepton mixing angle of the MNS mixing
matrix is well incorporated in a universal mixing hypothesis between quark and
lepton sectors. This hypothesis asserts that, in the charged lepton diagonal
base, all other mass matrices for up- and down-type quarks and light neutrinos
are diagonalized by the same unitary matrix except for the phase elements. It
is expressed as for
quark mixing matrix and lepton mixing matrix in the
phenomenological level. Here is a diagonal phase mass matrix.
is a slightly different phase parameter from the Dirac CP
violating phase (best fit) in the MNS lepton mixing matrix.Comment: 6 pages, 2 figures, accepted by MPL
Measuring the lower bound of the neutrino mass at the LHC in Higgs triplet model
We show in the framework of Higgs triplet model that the lower bound of the
neutrino mass is obtained if we can measure at the LHC.Comment: 5 pages, 2 figures, revised version in Pyhs.Rev.D. Using the reduced
luminosity of LHC, we added the estimation on the order of magnitude of the
