1207.1644 (S. Habib Mazharimousavi et al.)

Einstein-Yang-Mills-Scalar Black Holes with a potential    [PDF]

S. Habib Mazharimousavi, M. Halilsoy, T. Tahamtan
We find Einstein-Yang-Mills (EYM) black hole solutions endowed with massless scalar hair in the presence of a potential V(\phi) as function of the scalar field \phi. Choosing V(\phi) = constant (or zero) sets the scalar field to vanish leaving us with the EYM black holes. Our class of black hole solution has the feature that asymptotically, it is not flat, not anti-de Sitter (AdS) and not conformal to Lifshitz black holes. The role of the potential V(\phi) in making double bounces (i.e. both a minimum and maximum radii) on a DomainWall (DW) universe is highlighted.
