The Stability of the Weak Skyrmions
We consider a set of gauge invariant terms in higher order effective
Lagrangians of the strongly interacting scalar of the electroweak theory. The
terms are introduced in the framework of the hidden gauge symmetry formalism.
The usual gauge term is known to stabilize the skyrmion but only in the large
vector mass limit. We find that adding higher-order gauge terms is insufficient
to insure stability. We then proceed to analyze other gauge invariant
interaction terms. Some of the conclusions also apply to QCD skyrmions.Comment: 3 pages, revtex v3, (optional), LAVAL-PHY-11-9
