Abstract(s) :

(Anglais) 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 correspond in a four-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 nonexistence of finite mass hyperspherically symmetric black holes in SU(2) Einstein-Yang-Mills theory.
