II. The Standard Model in the Isotopic Foldy-Wouthuysen Representation   without Higgs Bosons in the Fermion Sector. Spontaneous Breaking of Parity   and "Dark Matter" Problems
  The Standard Model with massive fermions is formulated in the isotopic Foldy-Wouthuysen representation. SU(2)xU(1) - invariance of the theory in this representation is independent of whether fermions possess mass or not, and, consequently, it is not necessary to introduce interactions between Higgs bosons and fermions. The study discusses a possible relation between spontaneous breaking of parity in the isotopic Foldy-Wouthuysen representation and the composition of elementary particles of "dark matter".
