Research output: Contribution to journalArticlepeer-review


The present baryon asymmetry of the universe has finally been determined at the finite temperature electroweak phase transition. The strength of this transition plays a crucial role. The effective action is presented to higher orders, including wave function correction factors and the full g4, λ2 effective potential. An upper bound for the Higgs mass mH ≈ 70 GeV is concluded for the reliability of the perturbative approach. The finite temperature electroweak phase transition is studied on the lattice and the most important results of Monte-Carlo simulations are collected.
