Flavor Mixing of Quarks and Leptons
Harald Fritzsch, LMU Munich,
The mass matrices of the quarks and leptons have three "texture zeros", as expected e.g. in Grand Unified Theories. The flavor mixing angles are functions of the fermion masses. For the quarks the results are in good agreement with the experimental results.
The small neutrino masses are due to the "see-saw"-mechanism. We calculate the
values of the three Majorana neutrino masses: 1.4 meV - 9 meV - 51 meV. The
effective neutrino mass, relevant fo the neutrinoless double beta decay, is
about 25 times smaller than the present limit from the experiments.
