Ju n 20 09 Higher Dimensional Charged Rotating Dilaton Black Holes

In this paper, we present the metric for the n-dimensional charged slowly rotating dilaton black hole with N = [(n−1)/2] independent rotation parameters, associated with N orthogonal planes of rotation in the background of asymptotically flat and asymptotically (anti)-de Sitter spacetime. The mass, angular momentum and the gyromagnetic ratio of such a black hole are determined for the arbitrary values of the dilaton coupling constant. We find that the gyromagnetic ratio crucially depends on the dilaton coupling constant, α, and decreases with increasing α in any dimension. ∗ sheykhi@mail.uk.ac.ir
