Electroweak baryon number non-conservation and "topological condensates" in the early Universe

Abstract

Electroweak vacuum transition processes (sphalerons) in the early Universe provide a possible explanation of the baryon asymmetry. Anomaly theory suggests that these electroweak baryon number non-conserving processes are accompanied by the formation of a ``topological condensate'' which may remain in the Universe that we observe today.
