Entropy production at electroweak bubble walls from scalar field fluctuations
M. Eriksson, M. Laine
The real-time dynamics of an electroweak phase transition involves large time and distance scales, the domain of hydrodynamics. However, the matching conditions of ideal hydrodynam…

Computing singlet scalar freeze-out with plasmon and plasmino states
S. Biondini, M. Eriksson, M. Laine
The final-state particles from cosmological dark matter co-annihilation are expected to equilibrate. As dictated by Hard Thermal Loop resummation, the spectrum of equilibrated quas…

Soft contributions to the thermal Higgs width across an electroweak phase transition
M. Eriksson, M. Laine
We estimate the equilibration rate of a nearly homogeneous Higgs field, displaced from its ground state during the onset of an electroweak phase transition. The computation is carr…
