Standard Model with a Contracted Gauge Group

The hypothesis is discussed that the standard model formed as a result of the electroweak transition is valid at a higher temperature of the Universe, but with a contracted gauge group. The modified model predicts a temperature threshold of $$T \sim {{10}^{7}}$$ GeV, above which only half of the particles (neutrinos, Higgs boson, $$u$$ quark, and its color $$R$$ component), interacting by exchanging photons, neutral $$Z$$ bosons, and $$R$$ gluons, exert a predominant influence on the state of the space environment. The model does not disagree with the LHC data on Higgs boson creation cross sections at energies of 7, 8, 13, and 14 TeV.
