It is found that the binary dihedral group Q6, along with the assumption that the Higgs sector is of type II, predicts mass matrix of a nearest neighbor interaction type for quarks and leptons. We present a supersymmetric model based on Q6 with spontaneously induced CP phases. The quark sector contains 8 real parameters with one independent phase to describe the quark masses and their mixing. Predictions in the |Vub| - η̄, |Vub| - sin2β(φ1), and |Vub| - |V td/Vts| planes are given. The lepton sector contains also 9 parameters. A normal as well as an inverted spectrum of neutrino masses is possible, and we compute Ve3. We find that |Ve3| 2 > 10-4 in the case of a normal spectrum, and |V e3|2 > 8 × 10-4 in the case of an inverted spectrum. It is also found that Q6 symmetry forbids all Baryon number violating terms of d = 4, and the contributions to EDMs from the A terms vanish in this model. © 2005 The American Physical Society., 金沢大学大学院自然科学研究科物理学, 金沢大学理学部}, pages = {056006-1--056006-16}, title = {Dihedral families of quarks, leptons, and Higgs bosons}, volume = {71}, year = {2005} }
