Axion Decay in a Constant Electromagnetic Background Field and at Finite Temperature using World-line Methods
Michael Haack, Michael G. Schmidt
We investigate the radiative decay of the axion into two photons in an external electromagnetic field to one loop order. Our approach is based on the world-line formalism, which is…

Non-perturbative correlation masses in the hot electroweak phase
H. G. Dosch, J. Kripfganz, A. Laser +1
The effective action describing the long range fluctuations in the high temperature phase of the electroweak standard theory is a strongly coupled SU(2)-Higgs-model in three dimens…

Sphaleron Effects Near the Critical Temperature
Meik Hellmund, Jochen Kripfganz, Michael G. Schmidt
We discuss one-loop radiative corrections to the sphaleron-induced baryon number-violating transition rate near the electroweak phase transition in the standard model. We emphasize…
