Vacuum topology and the electroweak phase transition
Abstract
We investigate if the topology of pure gauge fields in the electroweak vacuum can play a role in classical dynamics at the electroweak phase transition. Our numerical analysis shows that magnetic fields are produced if the initial vacuum has nontrivial Chern-Simons number, and the fields are helical if the Chern-Simons number changes during the phase transition.
