Spatially compact solutions and stabilization in Einstein-Yang-Mills-Higgs theories | | Péter Forgács

5 Aug 2005 | | Journal: | Phys Rev Lett, 95 (6), 061101 | | Abstract: | New solutions to the static, spherically symmetric Einstein-Yang-Mills-Higgs equations with the Higgs field in the triplet (doublet) representation are presented. They form continuous families parametrized by alpha = M(W)/M(Pl) [M(W) (M(Pl)) denoting the W boson (the Planck) mass]. The corresponding space-times are regular and have spatially compact sections. A particularly interesting class with the Yang-Mills amplitude being nodeless is exhibited and is shown to be linearly stable with respect to spherically symmetric perturbations. For some solutions with nodes of the Yang-Mills amplitude a new stabilization phenomenon is found, according to which their unstable modes disappear as alpha increases (for the triplet) or decreases (for the doublet). | | Source: | PubMed, pmid16090934 | | Other source: | [GID 58570] gr-qc/0505007 | | Services: | Forum | Review | Favorites | |
