The sphaleron energy for SU(2)-Higgs from cooling

Abstract

The cooling algorithm for saddle points presented in ref. [1] is generalized to obtain static classical solutions of the SU(2)-Higgs field theory in the limit of infinite Higgs self-coupling. The sphaleron energy obtained via this algorithm is ${\mathcal{E}}_{\mathrm{sph}}=5.08(7)M_W/{\alpha }_W$ to be compared with 5.0707 obtained in the variational approach [2].
