Description
In the present talk, we consider the existence of the two
degenerate universal vacua: a) the first Electroweak vacuum at
$v=246$ GeV - "true vacuum", and b) the second Planck scale "false
vacuum" at $v_2\sim 10^{18}$ GeV. In these vacua, we investigated
the different topological defects. The main aim of this paper is
an investigation of the hedgehog's configurations as defects of the
false vacuum. In the framework of the $f(R)$ gravity, suggested by
authors in their Gravi-Weak Unification model, we obtained a black
hole solution, which corresponds to a "hedgehog" - global
monopole, "swallowed" by a black-hole with mass $\sim 10^{19}$
GeV. These black-holes form a lattice-like structure of the vacuum
at the Planck scale. Considering the results of the hedgehog
lattice theory in the framework of the SU(2) Yang-Mills
gauge-invariant theory with hedgehogs in the Wilson loops, we have
used the critical value of temperature for the hedgehog's
confinement phase. This result gave us the possibility to conclude
that there exist triplet Higgs fields which can contribute to the
SM at the energy scale $\simeq 10^4\sim 10^5$ GeV. Showing a new
physics at the scale $10\sim 100$ TeV, these triplet Higgs
particles can provide the stability of the EW-vacuum of the SM.
