An introduction to baryon violation in standard electroweak theory
Peter B. Arnold · University of North Texas Digital Library (University of North Texas) · 1990
I shall begin with a qualitative overview of the anomaly and B violation at zero and non-zero temperature, demonstrating how these processes may be understood on the back of an envelope. Then I shall discuss a part of the formalism necessary for doing calculations in more detail. Specifically, B violation is related to various solutions to the Euclidean equations of motion; instantons, sphalerons, and calorons (also called periodic instantons). The applicability of the various solutions may be understood by analogies with elementary quantum mechanics problems. Finally, I shall touch upon the computation of high-energy B violation mentioned above. 29 refs., 11 figs.
