  We perform comparative analyses of quantum loop corrections to some
observationally important two- and three-point Green functions within two
distinct symmetry-breaking mechanisms. It appears that the existing high-energy
data, neutrino experiments and present astrophysical and cosmological
constraints strongly disfavour the Higgs mechanism, while the introduction of
the noncontractible space as a symmetry-breaking mechanism can resolve all
known problems and puzzles of fundamental interactions.
