Hydromagnetic Turbulence
Recent progress in astrophysical hydromagnetic turbulence is being reviewed. The physical ideas behind the now widely accepted Goldreich–Sridhar model and its extension to compressible magnetohydrodynamic turbulence are introduced. Implications for cosmic ray diffusion and acceleration is being discussed. Dynamo-generated magnetic fields with and without helicity are contrasted against each oth...
متن کاملThe weak electroweak phase transition
We present a detailed analysis of the phase transition in the standard model at finite temperature. Using an improved perturbation theory, where plasma masses are determined from a set of one-loop gap equations, we evaluate the effective potential V ef f (ϕ, T) in next-to-leading order, i.e., including terms cubic in the gauge coupling g, the scalar self-coupling λ 1/2 and the top-quark Yukawa ...

متن کاملEffective Models of the Electroweak Phase Transition
The consecutive integration over the distinct mass scales O(T), O(gT) leads to a hierarchy of effective models for the electroweak phase transition. Different techniques for the realisation of such strategy are reviewed. Advantages and difficulties resulting from the use of reduced models are discussed.
متن کاملField Dynamics of the Electroweak Phase Transition
We investigate the thermodynamics and dynamics of the electroweak phase transition by modelling the infrared physics with classical Yang-Mills Higgs theory. We discuss the accuracy of this approach and conclude that, for quantities whose determination is dominated by the infrared, the classical method should be correct up to parametrically suppressed (ie O(α)) corrections. For a Higgs self-coup...
