Mass and CKM Matrices of Quarks and Leptons, the Leptonic CP-phase in neutrino oscillations
A general approach for construction of quark and lepton mass matrices is
formulated. The hierarchy of quarks and charged leptons ("electrons") is large,
it leads using the experimental values of mixing angles to the hierarchical
mass matrix slightly deviating from one's suggested earlier by Stech and
including naturally the CP-phase.
The same method based on the rotation of generation numbers in the diagonal
mass matrix is used in the electron-neutrino sector of theory, where neutrino
mass matrix is determined by the Majorano see-saw approach. The hierarchy of
neutrino masses, much smaller than for quarks, was used including all existing
(even preliminary) experimental data on neutrinos mixing.
The leptonic mass matrix found in this way includes not known value of the
leptonic CP-phase. It leads to a large oscillations and
suppresses the and also oscillations. The
explicit expressions for the probabilities of neutrino oscillation were
obtained in order to specify the role of leptonic CP-phase. The value of time
reversal effect (proportional to ) was found to be small . However, a dependence of the values of
transition probabilities, averaged over oscillations, on the leptonic CP-phase
has found to be not small - of order of tens percent.Comment: 21 pages, 2 figures, some correction
