Cosmological phase transitions and baryogenesis
- Instituto de Estructura de la Materia (CSIC), Serrano 123, E-28006 Madrid (Spain)
We review various aspects of field theory at finite temperature related to the theory of phase transitions. In particular, the real and imaginary time formalisms are discussed, showing their equivalence in simple examples. Bubble nucleation by thermal tunneling, and the subsequent development of the phase transition is described in some detail. Some attention is also devoted to the breakdown of the perturbative expansion and the infrared problem in the finite temperature field theory. Finally the application to baryogenesis at the electroweak phase transition is done in the Standard Model and in the Minimal Supersymmetric Standard Model. In all cases we have translated the condition of not washing out any previously generated baryon asymmetry by upper bounds on the Higgs mass.
