On Spherically-Symmetric Solutions in the Two-Higgs Standard Model
Abstract
We report the results of a numerical search for non-topological solitons in the two-Higgs standard model, characterized by the non-trivial winding, π3(S3), of the relative phase of the two doublets. In a region of (weak-coupling) parameter space we identify a branch of winding solutions, which are lower in energy than the embedded standard sphaleron and deformed (bi)sphalerons. Contrary, however, to what happens in 2d toy models, these solutions remain unstable even for very large Higgs masses.
