A sphaleron for the non-Abelian anomaly
- Christian Rupp (Universität Karlsruhe, Karlsruhe, Germany)
Abstract
Sphalerons are static but unstable finite-energy solutions of the classical Yang-Mills-Higgs field equations. Via the phenomenon of spectral flow, sphalerons are linked to the possible existence of anomalies. After illustrating this interconnection for the well-known example of the chiral $U(1)$ anomaly, I will discuss a possible sphaleron solution related to the non-Abelian (Bardeen) anomaly in SU(3) gauge theory.
