Symmetry restoration processes during the non-equilibrium stage of " pre-heating " after inflation is studied. It is shown that symmetry restoration is very efficient when the majority of created particles are concentrated at energies much smaller than the temperature T in equilibrium. The strength of symmetry restoration measured in terms of the equivalent… CONTINUE READING
