|Title:||Reissner-Nordstrom black holes with non-Abelian hair|
Tchrakian, D. H.
|Abstract:||We consider d >= 4 Einstein-(extended-)Yang-Mills theory, where the gauge sector is augmented by higher order terms. Linearisingthe (extended) Yang- Mills equations on the background of the electric Reissner-Nordstrm (RN) black hole, we show the existence of normalisable zero modes, dubbed non-Abelian magnetic stationary clouds. The non-linear realisationof these clouds bifurcates the RN family into a branch of static, spherically symmetric, electrically charged and asymptotically flat black holes with non-Abelian hair. Generically, the hairy black holes are thermodynamically preferred over the RN solution, which, in this model, becomes unstable against the formation of non-Abelian hair, for sufficiently large values of the electric charge.
