Scientific paper

We have performed a new exact evaluation of the fluctuation determinant $\kappa$ of the electroweak sphaleron with $\Theta _W =0$. The results differ significantly from a previous calculation of this quantity by Carson et. al. . We find that $\kappa$ is of order 1 in units $(gv)^6$ while the previous results indicated a strong suppression of the sphaleron transition by this factor.
