Einstein-Yang-Mills-Dilaton Sphalerons and Black Holes
نویسندگان
چکیده
SU(3) Einstein-Yang-Mills-dilaton theory possesses sequences of static spherically symmetric sphaleron and black hole solutions for the SU(2) and the SO(3) embedding. The solutions depend on the dilaton coupling constant γ, approaching the corresponding Einstein-Yang-Mills solutions for γ → 0, and Yang-Millsdilaton solutions in flat space for γ → ∞. The sequences of solutions tend to Einstein-Maxwell-dilaton solutions with different magnetic charges. The solutions satisfy analogous relations between the dilaton field and the metric for general γ. Thermodynamic properties of the black hole solutions are discussed. Preprint hep-th/9510069

Gravitating Non-Abelian Solitons and Black Holes with Yang-Mills Fields
We present a review of gravitating particle-like and black hole solutions with nonAbelian gauge fields. The emphasis is given to the description of the structure of the solutions and to the connection with the results of flat space soliton physics. We describe the Bartnik-McKinnon solitons and the non-Abelian black holes arising in the Einstein-Yang-Mills theory, and consider their various gene...
متن کاملInternal structure of Einstein-Yang-Mills-Dilaton black holes
We study the interior structure of the Einstein-Yang-Mills-Dilaton black holes as a function of the dilaton coupling constant γ ∈ [0, 1]. For γ 6= 0 the solutions have no internal Cauchy horizons and the field amplitudes follow a power law behavior near the singularity. As γ decreases, the solutions develop more and more oscillation cycles in the interior region, whose number becomes infinite i...
متن کاملNegative modes around Einstein–Yang–Mills sphalerons and black holes
The dynamics of small perturbations around sphaleron and black hole solutions in the Einstein-Yang-Mills theory for the gauge group SU(2) is investigated. The perturbations can be split into the two independent sectors in accordance with their parity; each sector contains negative modes. The even-parity negative modes are shown to correspond to the negative second variations of the height of th...
متن کاملBlack strings in (4 + 1)−dimensional Einstein-Yang-Mills theory
We study two classes of static uniform black string solutions in a (4 + 1)-dimensional SU(2) EinsteinYang-Mills model. These configurations possess a regular event horizon and corresponds in a 4−dimensional picture to axially symmetric black hole solutions in an Einstein-Yang-Mills-Higgs-U(1)-dilaton theory. In this approach, one set of solutions possesses a nonzero magnetic charge, while the o...
متن کاملEinstein-Yang-Mills Sphalerons and Black Holes
In the SU(3) Einstein-Yang-Mills system sequences of static spherically symmetric regular solutions and black hole solutions exist for both the SU(2) and the SO(3) embedding. We construct the lowest regular solutions of the SO(3) embedding, missed previously, and the corresponding black holes. The SO(3) solutions are classified according to their boundary conditions and the number of nodes of t...
