Chern-Simons and Winding Number in a Tachyonic Electroweak Transition

Meindert van der Meulen, Denes Sexty, Jan Smit +1

We investigate the development of winding number and Chern-Simons number in a tachyonic transition in the SU(2) Higgs model, motivated by the scenario of cold electroweak baryogene…
