چکیده
Cold Electroweak Baryogenesis is an attempt to explain the cosmological baryon asymmetry using only a minimal extension of the Standard Model. The relevant processes take place out of thermal equilibrium and are non-perturbative, and so must be studied using full, real-time lattice simulations. We present new results on the dependence on CP-violation and the Higgs-toW mass ratio. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

A system of two static quarks, at fixed distances r, and two light quarks is studied on an anisotropic lattice. Excitations by operators emphasizing quark or gluon degrees of freedom are examined. The maximum entropy method is applied in the spectral analysis. These simulations ultimately aim at learning about mechanisms of hadronic interaction.

Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar M H. There is presumably no true symmetry restoration at high temperature. Nevertheless , a first order phase transition occurs in the standard model for M H ∼ < 70 GeV. For a realistic scalar mass M H ∼ > 70 GeV the transition to the high temperature regime is desc...

A consistent description of the confining QCD vacuum as a dual superconductor requires a determination of fundamental parameters such as the superconductor correlation length ξ and the field penetration depth λ, which determine whether the superconductor is of type I or type II. We illustrate preliminary results of a lattice determination of ξ for the case of pure Yang-Mills with two colors, ob...
