3 Jun 2004 | | Journal: | Phys. Rev. D70 (2004), 084003 | | Subject: | hep-th | | Affiliation: | Universite de Mons, Belgium), Fabien Clement (Universite de Mons, Belgium) and Betti Hartmann (IUB, Germany | | Abstract: | We study the Einstein-Yang-Mills equations in a 6-dimensional space-time. We make a self-consistent static, spherically symmetric ansatz for the gauge fields and the metric. The metric of the manifold associated with the two extra dimensions contains off-diagonal terms. The classical equations are solved numerically and several branches of solutions are constructed. We also present an effective 4-dimensional action from which the equations can equally well be derived. This action is a standard Einstein-Yang-Mills-Higgs theory extended by three scalar fields. Two of the scalar fields are interpreted as dilatons, while the one associated with the off-diagonal term of the metric induces very specific interactions. | | Source: | arXiv, hep-th/0406034 | | Services: | Forum | Review | PDF | Favorites | |
