ON SPHERICALLY-SYMMETRICAL SOLUTIONS IN THE 2-HIGGS STANDARD MODEL

We report the results of a numerical search for non-topological solito ns in the two-Higgs standard model, characterized by the non-trivial w inding, pi(3)(S-3), Of the relative phase of the two doublets. In a re gion of (weak-coupling) parameter space we identify a branch of windin g solutions, which are lower in energy than the embedded standard spha leron and deformed (bi)sphalerons. Contrary, however, to what happens in 2d toy models, these solutions remain unstable even for very large Higgs masses.
