A Critical Look at the Electroweak Phase Transition
Andreas Ekstedt, Johan Löfgren
The electroweak phase transition broke the electroweak symmetry. Perturbative methods used to calculate observables related to this phase transition suffer from severe problems suc…

On the relationship between gauge dependence and IR divergences in the -expansion of the effective potential
Andreas Ekstedt, Johan Löfgren
Perturbative calculations of the effective potential evaluated at a broken minimum, , are plagued by difficulties. It is hard to get a finite and gauge invariant…
