概要
- 論文の詳細を見る
Hypotheses of the universal seesaw mechanism and the universal strength for Yukawa couplings are applied to explain one possible origin of quasi-democratic mass matrices of a special type in a left-right symmetric model with the gauge group SU(3)_c × SU(2)_L × SU(2)_R × U(1). Two kinds of Higgs doublets are postulated to mediate scalar interactions between the i-th generation of light fermion doublets and the j-th generation of heavy femion singlets with relative Yukawa coupling constants of the exponential form e^<iφ_<ij>>, where φ_<ij> are real phase constants. The lowest seesaw approximation results effectively in self-adjoint mass matrices which are quasi-democratic and have the same diagonal elements. A set of values for the parameters φ_<ij> is found which reproduces the present experimental data for the absolute values of the CKM matrix elements, the Jarlskog parameter and the Wolfenstein parameters.
