23 Dec 2004 | | Journal: | Phys.Lett. B609 (2005) 442-448 | | Subject: | hep-th hep-ph | | Abstract: | We study numerically the topological knot solution suggested recently in the Weinberg-Salam model. Applying the SU(2) gauge invariant Abelian projection we demonstrate that the restricted part of the Weinberg-Salam Lagrangian containing the interaction of the neutral boson with the Higgs scalar can be reduced to the Ginzburg-Landau model with the hidden SU(2) symmetry. The energy of the knot composed from the neutral boson and Higgs field has been evaluated by using the variational method with a modified Ward ansatz. The obtained numerical value is 39 Tev which provides the upper bound on the electroweak knot energy. | | Source: | arXiv, hep-th/0412282 | | Services: | Forum | Review | PDF | Favorites | |
