“…The two branches of solutions meet at a maximal value of the horizon radius. For small gravitational coupling the second branch can be extended all the way back to vanishing horizon radius where it bifurcates with a globally regular solution [28,24]. For larger gravitational coupling, the second branch terminates into an embedded abelian solution of Einstein-Maxwell dilaton type.…”

We review the properties of static, higher dimensional black hole solutions in theories where non-abelian gauge fields are minimally coupled to gravity. It is shown that black holes with hyperspherically symmetric horizon topology do not exist in $d > 4$, but that hyperspherically symmetric black holes can be constructed numerically in generalized Einstein-Yang-Mills models. 5-dimensional black strings with horizon topology S^2 x S^1 are also discussed. These are so-called undeformed and deformed non-abelian black strings, which are translationally invariant and correspond to 4-dimensional non-abelian black holes trivially extended into one extra dimensions. The fact that black strings can be deformed, i.e. axially symmetric for constant values of the extra coordinate is a new feature as compared to black string solutions of Einstein (-Maxwell) theory. It is argued that these non-abelian black strings are thermodynamically unstable.Comment: 8 pages; prepared as contribution to the proceedings of the Spanish Relativity Meeting (ERE), Salamanca, 200

“…A black string, as a black object [1][2][3][4][5][6] is the simplest extension, of a black hole, with the addition of a compact, killing coordinate. This definition does not include the non-uniform black strings in which the metric functions are explicitly dependent on the extra-coordinate [7][8][9].…”

We present d+1−dimensional pure magnetic Yang-Mills (YM) black strings (or 1−branes) induced by the d−dimensional Einstein-Yang-Mills-Dilaton black holes. Born-Infeld version of the YM field makes our starting point which goes to the standard YM field through a limiting procedure. The lifting from black holes to black strings, (with less number of fields) is by adding an extra, compact coordinate. This amounts to the change of horizon topology from S d−2 to a product structure. Our black string in 5−dimensions is a rather special one, with uniform Hawking temperature and non-asymptotically flat structure. As the YM charge becomes large the string gets thinner to tend into a breaking point and transform into a 4−dimensional black hole.

“…dΩ 2 d−2 is a constant. Non-Abelian gauge fields were considered as BS solutions by other researchers [12][13][14][15]. Our approach, however, differs from other studies where we present exact non-Abelian solutions in all dimensions.…”

We present a class of non-asymptotically flat (NAF) charged black p-branes (BpB) with p-compact dimensions in higher dimensional Einstein-Yang-Mills theory. Asymptotically the NAF structure manifests itself as an anti-de-sitter spacetime. We determine the total mass / energy enclosed in a thin-shell located outside the event horizon. By comparing the entropies of BpB with those of black holes in same dimensions we derive transition criteria between the two types of black objects. Given certain conditions satisfied our analysis shows that BpB can be considered excited states of black holes. An event horizon r+ versus charge square Q 2 plot for the BpB reveals such a transition where r+ is related to the horizon radius r h of the black hole (BH) both with the common charge Q.
