Energy barrier in the two-Higgs model
arXiv:hep-ph/9808295 · doi:10.1142/S021773239900153X
Abstract
The electroweak model is extended by a second Higgs doublet and a numerical investigation of static, finite energy classical solutions is performed. The results indicate that for a large domain of the parameters of the Higgs potential, the energy barrier between topologically distinct vacua of the Lagrangian is constituted by a bisphaleron.
