The MSSM electroweak phase transition

When the Minimally Supersymmetric Standard Model (MSSM) is placed in an environment with a finite temperature T approximately=100 GeV, the electroweak symmetry gets restored. Depending on the parameter values, this can happen either via a first order phase transition, or an analytic crossover. If th...

description When the Minimally Supersymmetric Standard Model (MSSM) is placed in an environment with a finite temperature T approximately=100 GeV, the electroweak symmetry gets restored. Depending on the parameter values, this can happen either via a first order phase transition, or an analytic crossover. If there is a phase transition which is sufficiently strongly of the first order, important cosmological remnants could be produced, such as a baryon asymmetry. In this talk I review which part of the MSSM parameter space is consistent both with cosmological baryon asymmetry generation and with existing experimental data. (18 refs).
