Quantum Corrections to the Electroweak Sphaleron Transition
J. Baacke, S. Junker
Abstract
We have performed a new exact evaluation of the fluctuation determinant κ of the electroweak sphaleron with ΘW =0. The results differ significantly from a previous calculation of this quantity by Carson et. al. . We find that κ is of order 1 in units (gv)6 while the previous results indicated a strong suppression of the sphaleron transition by this factor.
