PROPOSAL OF UNIFIED FERMION TEXTURE

A unified form of mass matrix is proposed for neutrinos, charged lepto ns, up quarks and down quarks. Some constraints for the parameters inv olved are tentatively postulated. Then, the predictions are neatly con sistent with available experimental data. Among the predictions are: ( i) m(tau) similar or equal to 1776.80 MeV (with the inputs of m(e) and m(mu)), (ii) m(nu 0) much less than m(nu 1) similar to (0.6 to 4) x 1 0(-2) eV and m(nu 2) similar to (0.2 to 1) x 10(-1) eV (with the atmos pheric-neutrino inputs of \m(nu 2)(2) - m(nu 1)(2)\ similar to (0.0003 to 0.01) eV(2) and the nu(mu) --> nu(tau) oscillation amplitude simil ar to 0.8), and also (iii) m(s) similar or equal to 270 MeV, \V-ub/V-c b\ similar or equal to 0.082 and argV(ub) similar or equal to -64 degr ees (with the inputs of m(c) = 1.3 GeV, m(b) = 4.5 GeV, \V-us\ = 0.221 and \V-cb\ = 0.041, where m(u) much less than m(c) much less than m(t ) and m(d) much less than m(s) much less than m(b)). All elements of t he Cabibbo-Kobayashi-Maskawa matrix are evaluated. All elements of its lepton counterpart are calculated up to an unknown phase (Appendix B) . Some items related to dynamical aspects of the proposed fermion ''te xture'' are briefly commented on (Appendix A). In particular, the noti on of a novel dark matter, free of any Standard Model interactions (an d their supersymmetric variants), appears in the case of preen option.
