Abstract
The infinite energy limit of the Electroweak Model with the contracted gauge group is regarded at the level of classical gauge fields. Masses of all particles of the Electroweak Model disapper under contraction, so the Lagrangian of the limit model includes massless neutral Z-bosons, massless u-quarks, neutrinos and photons as well as weak and electromagnetic interactions. The weak interactions become long-range and are mediated by neutral currents. The limit model represents the development of the early Universe from the Big Bang up to the end of the first second.
