Abstract: We discuss the construction of non-Abelian black holes and globally regular monopole solutions to N = 2 d = 4 EYM theories. Special emphasis is put on how the attractor mechanism works for the non-Abelian black holes.

“…The ground state of this supergravity truncation does not have a constant scalar and so there is no AdS 4 vacuum. (For work on non-abelian BPS black holes and Dirac-'t Hooft type monopoles in D = 4, N = 2 ungauged supergravity, see [3] and references therein. )…”

We investigate static non-abelian black hole solutions of anti-de Sitter Einstein-YangMills-Dilaton gravity, which is obtained as a consistent truncation of five-dimensional maximal gauged supergravity. If the dilaton is (consistently) set to zero, the remaining equations of motion, with a spherically-symmetric ansatz, may be derived from a superpotential. The associated first-order equations admit an explicit solution supported by a non-abelian SU (2) gauge potential, which has a logarithmically growing mass term. In an extremal limit the horizon geometry becomes AdS 2 × S 3 . If the dilaton is also excited, the equations of motion cannot easily be solved explicitly, but we obtain the asymptotic form of the more general non-abelian black holes in this case. An alternative consistent truncation, in which the Yang-Mills fields are set to zero, also admits a description in terms of a superpotential. This allows us to construct explicit wormhole solutions (neutral spherically-symmetric domain walls). These solutions may be generalised to dimensions other than five.
