Quantum fluctuations of the electroweak sphaleron: Erratum and Addendum
J. Baacke, S. Junker
TL;DR
The overall agreement between the two existing exact computations and their consistency with the estimate is improved considerably.
Abstract
We correct an error in our treatment of the tadpole contribution to the fluctuation determinant of the sphaleron, and also a minor mistake in a previous estimate. Thereby the overall agreement between the two existing exact computations and their consistency with the estimate is improved considerably.
