abstractabstract It may appear that the recently found resonance at 125 GeV is not the only Higgs boson. The masses of
the Higgses may be related to the mass of t — quark as
(The sum is within a group of the scalar excitations.) This rule is the analogue of the sum rule in He3-B
(for the excitations of the same total momentum J). It was originally proposed by Nambu for He3-B. We call it the Nambu sum rule.

Conclusions1. The notion of the Nambu Sum rule is introduced. It works in:
- Helium superfluid 3-B, 3-A, in thin films 3-b,3-a
- QCD at finite chemical potential (normal phase, small T, small mu),
- color superconductor (CFL phase)
- the considered models of top — quark condensation
2. Lessons for the TeV — scale physics:
- The 125 GeV Higgs cannot be the Nambu partner of the neutral
Goldstone boson
- If there are two twice degenerated Higgs bosons, then the Namby partner of the 125 GeV Higgs should have mass 210 GeV
-If there are only two states, then the second Higgs should have mass 325 GeV
-If there are two Higgs bosons of equal masses, these masses are around 245 GeV

ConclusionsConclusions1. The dynamical SO(3,1) gauge theory with the scale >1000
TeV and the torsion mass ~ this scale is coupled in a nonminimal way to fermions.
2. Due to the effecitve 4 – fermion interactions fermions are condensed and provide the DEWSB.
3. In zero order approximation all fermions acquire equal masses.
4. When the corrections due to the other gauge fields are taken into account, the hierarchy of fermion masses appears.
5. The given gauge theory is unusual since it should provide chiral symmetry breaking but cannot be confining.
