The high-temperature limit of the Standard Model generated by the contractions of gauge groups is discussed. Contraction parameters of gauge group SU(2) of the Electroweak Model and gauge group SU(3) of Quantum Chromodynamics are taken identical and tending to zero when the temperature increases. Properties of the elementary particles change drastically at the infinite temperature limit: all particles lose masses, all quarks are monochromatic. Electroweak interactions become long-range and are… Expand
High temperature limit of the Standard Model due to gauge groups contraction
The high temperature (high energy) limit of the Standard Model is developed with the help of contractions its gauge groups. The elementary particles evolution in the early Universe from Plank time upExpand

Natural limits of Electroweak Model as contraction of its gauge group
The low and higher energy limits of the Electroweak Model are obtained from first principles of gauge theory. Both limits are given by the same contraction of the gauge group, but for the differentExpand
Limiting case of modified electroweak model for contracted gauge group
The modification of the Electroweak Model with 3-dimensional spherical geometry in the matter fields space is suggested. The Lagrangian of this model is given by the sum of the free (without anyExpand
Contraction of electroweak model and neutrino
The electroweak model, which lepton sector correspond to the contracted gauge group SU(2; j) × U(1), j → 0, whereas boson and quark sectors are standard one, is suggested. The field space of theExpand

Analog of Electroweak model for contracted gauge group
The limiting case of the bosonic part of the standard Electroweak Model, which corresponds to the contracted gauge group SU(@#@ 2; j) × U(1) is discussed. The Higgs-boson, Z-boson, andExpand
Interpretation of neutrino-matter interactions at low energies as contraction of gauge group of Electroweak Model
The very weak neutrino-matter interactions are explained with the help of the gauge group contraction of the standard Electroweak Model. The mathematical contraction procedure is connected with theExpand

The purpose of the present note is to investigate, in some generality, in which sense groups can be limiting cases of other groups, and how their representations can be obtained from the representations of the groups of which they appear as limits. Expand
