Physical vacuum as the source of the standard model particle masses
  We present an approach of mass generation for Standard Model particles in which fermions acquire masses from their interactions with physical vacuum and gauge bosons acquire masses from charge fluctuations of vacuum. A remarkable fact of this approach is that left-handed neutrinos are massive because they have a weak charge. We obtain consistently masses of electroweak gauge bosons in terms of fermion masses and running coupling constants of strong, electromagnetic and weak interactions. On the last part of this work we focus our interest to present some consequences of this approach as for instance we first show a restriction about the possible number of fermion families. Next we establish a prediction for top quark mass and finally fix the highest limit for the summing of the square of neutrino masses.
