Hints from the Standard Model for Particle Masses and Mixings
  The standard model taken with a momentum space cut-off may be viewed as an effective low energy theory. The structure of it and its known parameters can give us hints for relations between these parameters. In the present investigation the Higgs problem will be discussed, the possible connection of the Higgs meson with the heavy top quark, and the geometric structure of the quark and lepton mass matrices.
