Soft scalar-field corrections to the topological susceptibility
Dietrich Bodeker, Rasmus S. K. Nielsen
We compute the contribution from soft scalar-field fluctuations to the topological susceptibility in SU(2) gauge theory at high temperature. We construct a 3-dimensional effective…
Baryon number freeze-out in the Standard Model, precisely
Cristina Benso, Dietrich Bödeker, Kohei Kamada +4
Weak sphaleron transitions turn a lepton asymmetry of the Standard Model plasma in the early Universe into a baryon asymmetry, conserving baryon-minus-lepton number and its i…
Scalar field damping at high temperatures
Dietrich Bodeker, Jan Nienaber
The motion of a scalar field that interacts with a hot plasma, like the inflaton during reheating, is damped, which is a dissipative process. At high temperatures the damping can b…
Baryogenesis from the weak scale to the grand unification scale
Dietrich Bodeker, Wilfried Buchmuller
We review the current status of baryogenesis with emphasis on electroweak baryogenesis and leptogenesis. The first detailed studies were carried out for SU(5) GUT models where CP-v…
The cosmic QCD transition for large lepton flavour asymmetries
Mandy M. Middeldorf-Wygas, Isabel M. Oldengott, Dietrich Bödeker +1
We study the impact of large lepton flavour asymmetries on the cosmic QCD transition. Scenarios of unequal lepton flavour asymmetries are observationally almost unconstrained and t…
Status of rates and rate equations for thermal leptogenesis
Simone Biondini, Dietrich Bodeker, Nora Brambilla +8
In many realizations of leptogenesis, heavy right-handed neutrinos play the main role in the generation of an imbalance between matter and antimatter in the early Universe. Hence,…
Electroweak Bubble Wall Speed Limit
Dietrich Bodeker, Guy D. Moore
In extensions of the Standard Model with extra scalars, the electroweak phase transition can be very strong, and the bubble walls can be highly relativistic. We revisit our previou…
Lepton asymmetry rate from quantum field theory: NLO in the hierarchical limit
Dietrich Bodeker, Marc Sangel
The rates for generating a matter-antimatter asymmetry in extensions of the Standard Model (SM) containing right-handed neutrinos are the most interesting and least trivial coeffic…
Equilibration, particle production, and self-energy
D. Bodeker, M. Sangel, M. Wormann
The discontinuity, or imaginary part of a self-energy at finite temperature is proportional to the rate at which the corresponding particles are produced when very few of them are…
Order g^2 susceptibilities in the symmetric phase of the Standard Model
D. Bodeker, M. Sangel
Susceptibilities of conserved charges such as baryon minus lepton number enter baryogenesis computations, since they provide the relationship between conserved charges and chemical…
Kubo relations and radiative corrections for lepton number washout
D. Bodeker, M. Laine
The rates for lepton number washout in extensions of the Standard Model containing right-handed neutrinos are key ingredients in scenarios for baryogenesis through leptogenesis. We…
Sommerfeld effect in heavy quark chemical equilibration
D. Bodeker, M. Laine
The chemical equilibration of heavy quarks in a quark-gluon plasma proceeds via annihilation or pair creation. For temperatures T much below the heavy quark mass M, when kineticall…
Heavy quark chemical equilibration rate as a transport coefficient
D. Bodeker, M. Laine
Motivated by indications that heavy (charm and bottom) quarks interact strongly at temperatures generated in heavy ion collision experiments, we suggest a non-perturbative definiti…
Thermal production of ultrarelativistic right-handed neutrinos: Complete leading-order results
Denis Besak, Dietrich Bodeker
The thermal production of relativistic right-handed Majorana neutrinos is of importance for models of thermal leptogenesis in the early Universe. Right-handed neutrinos can be prod…
Hard thermal loops for soft or collinear external momenta
Denis Besak, Dietrich Bodeker
We consider finite temperature 1-loop diagrams with hard loop momenta and an arbitrary number of external gauge fields when the external momenta are either soft, or near the light…
Perturbative and non-perturbative aspects of the non-abelian Boltzmann-Langevin equation
Dietrich Bodeker
We study the Boltzmann-Langevin equation which describes the dynamics of hot Yang-Mills fields with typical momenta of order of the magnetic screening scale g^2 T. It is transforme…
Finite baryon density effects on gauge field dynamics
D. Bodeker, M. Laine
We discuss the effective action for QCD gauge fields at finite temperatures and densities, obtained after integrating out the hardest momentum scales from the system. We show that…
Hard Thermal Loops and the Sphaleron Rate on the Lattice
D. Bodeker, G. D. Moore, K. Rummukainen
We measure the sphaleron rate (topological susceptibility) of hot SU(2) gauge theory, using a lattice implementation of the hard thermal loop (HTL) effective action. The HTL degree…
Chern-Simons Number Diffusion and Hard Thermal Loops on the Lattice
D. Bodeker, Guy D. Moore, K. Rummukainen
We develop a discrete lattice implementation of the hard thermal loop effective action by the method of added auxiliary fields. We use the resulting model to measure the sphaleron…
Renormalisation of the Nonperturbative Thermal Pressure
D Boedeker, P V Landshoff, O Nachtmann +1
We show how the fully resummed thermal pressure is rendered ultraviolet finite by standard zero-temperature renormalisation. The analysis is developed in a 6-dimensional scalar mod…
Effective dynamics of soft non-abelian gauge fields at finite temperature
Dietrich Bodeker
We consider time dependent correlation functions of non-abelian gauge fields at finite temperature. An effective theory for the soft () field modes is derived by integ…
Plasmon properties in classical lattice gauge theory
D. Bodeker, M. Laine
In order to investigate the features of the classical approximation at high temperatures for real time correlation functions, the plasmon frequencies and damping rates were recentl…
The finite temperature real time \hbar^2 corrections in quantum mechanics
D. Bodeker, M. Laine, O. Philipsen
We study non-perturbative real time correlation functions at finite temperature. In order to see whether the classical term gives a good approximation in the high temperature limit…
The 2-loop MSSM finite temperature effective potential with stop condensation
D. Bodeker, P. John, M. Laine +1
We calculate the finite temperature 2-loop effective potential in the MSSM with stop condensation, using a 3-dimensional effective theory. We find that in a part of the parameter s…
