4 Aug 2005 | | Journal: | Phys.Rev. D72 (2005) 104008 | | Subject: | hep-th gr-qc | | Affiliation: | Universite de Mons, Belgium), B. Hartmann (International University Bremen, Germany) and E. Radu (National University of Ireland Maynooth, Ireland | | Abstract: | We study two classes of static uniform black string solutions in a (4+1)-dimensional SU(2) Einstein-Yang-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 other solutions represent black holes located in between a monopole-antimonopole pair. A detailed analysis of the solutions’ properties is presented, the domain of existence of the black strings being determined. New four dimensional solutions are found by boosting the five dimensional configurations. We also present an argument for the non-existence of finite mass hyperspherically symmetric black holes in SU(2) Einstein-Yang-Mills theory. | | Source: | arXiv, hep-th/0508028 | | Services: | Forum | Review | PDF | Favorites | |
