“…The solutions obtained from this correspond to the static, spherically symmetric dyonic solutions obtained in [13]- [16] and which were thoroughly investigated in [17]. These solutions are a special case of the more general rotating solutions which will be given in the next section and so we will postpone any detailed discussion of them and their derivation until then.…”

The most general electrically and magnetically charged rotating black hole solutions of 5 dimensional Kaluza-Klein theory are given in an explicit form. Various classical quantities associated with the black holes are derived. In particular, one finds the very surprising result that the gyromagnetic and gyroelectric ratios can become arbitrarily large. The thermodynamic quantities of the black holes are calculated and a Smarr-type formula is obtained leading to a generalized first law of black hole thermodynamics. The properties of the extreme solutions are investigated and it is shown how they naturally separate into two classes. The extreme solutions in one class are found to have two unusual properties: (i). Their event horizons have zero angular velocity and yet they have non-zero ADM angular momentum. (ii). In certain circumstances it is possible to add angular momentum to these extreme solutions without changing the mass or charges and yet still maintain an extreme solution. Regarding the extreme black holes as elementary particles, their stability is discussed and it is found that they are stable provided they have sufficient angular momentum. *dar17@amtp.cam.ac.uk

“…• The non-supersymmetric extreme solutions, i.e., those with β → 0, P 2 = Q 1 = 0, |Q 2 | − |P 1 | → 0 and δ 1 → ∞, while keeping βe 2|δ 1 | and (|Q 2 | − |P 1 |)e 2|δ 1 | as finite parameters, reduce to the extreme dyonic five-dimensional Kaluza-Klein black hole studied in Ref. [29], after S-and T -duality transformations are imposed.…”

“…In the case when Q 2 = 0, P 1 has to be zero automatically due to our initial assumption that |Q 2 | ≥ |P 1 |. Then, the zero Taub-Nut constraint (29) does not restrict the values of δ 1,2 . In this case, we have non-extreme four-parameter solution with non-zero charges given by P…”

General static spherically symmetric black holes of the heterotic string on a six-torus

We present the most general static, spherically symmetric solutions of heterotic string compactified on a six-torus that conforms to the conjectured "no-hair theorem", by performing a subset of O(8, 24) transformations, i.e., symmetry transformations of the effective three-dimensional action for stationary solutions, on the Schwarzschild solution. The explicit form of the generating solution is determined by six SO(1, 1) ⊂ O(8, 24) boosts, with the zero Taub-NUT charge constraint imposing one constraint among two boost parameters. The non-nontrivial scalar fields are the axion-dilaton field and the moduli of the two-torus. The general solution, parameterized by unconstrained 28 magnetic and 28 electric charges and the ADM mass compatible with the Bogomol'nyi bound, is obtained by imposing on the generating solution [SO(6) × SO (22)]/[SO(4) × SO(20)] ⊂ O(6, 22) (T -duality) transformation and SO(2) ⊂ SL(2, R) (S-duality) transformation, which do not affect the four-dimensional space-time. Depending on the range of boost parameters, the non-extreme solutions have the space-time of either Schwarzschild or Reissner-Nordström black hole, while extreme ones have either null (or naked) singularity, or the space-time of extreme Reissner-Nordström black hole.

“…Such dyonic black holes have been considered in this context in [34][35][36][37][38][39]. The relevant black hole solution is that of [40,41,42], and, for the extreme black hole, the mass M satisfies…”

Limits of a system of N Dn-branes in which the bulk and string degrees of freedom decouple to leave a 'matter' theory are investigated and, for n > 4, either give a free theory or require taking N → ∞. The decoupled matter theory is described at low energies by the N → ∞ limit of n + 1 dimensional super Yang-Mills, and at high energies by a free type II string theory in a curved space-time.Metastable bound states of D6-branes with mass M and D0-branes with mass m are shown to have an energy proportional to M 1/3 m 2/3 and decouple, whereas in matrix theory they only decouple in the large N limit.fixed, giving the 't Hooft limit [24] of the super Yang-Mills theory, in which only the planar Feynman diagrams survive. In this limit, for large but finite N, the bulk and/or string modes do not decouple and are presumably crucial to the consistency of the theory, but in the infinite N limit, the bulk and string modes all
