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
