“…However, restricting the situation to the scattering of low-energy particles with zero angular momentum off extremal black holes one can get a more tractable problem. This was the main reason to analyse dilatonic black holes [8,9]. The problem can be reduced then to study a two-dimensional effective theory which turns out to be solvable [10,11,12,13,14,15,16].…”

We study the near-horizon AdS 2 ×S 2 geometry of evaporating near-extremal Reissner-Nordström black holes interacting with null matter. The non-local (boundary) terms t ± , coming from the effective theory corrected with the quantum Polyakov-Liouville action, are treated as dynamical variables. We describe analytically the evaporation process which turns out to be compatible with the third law of thermodynamics, i.e., an infinite amount of time is required for the black hole to decay to extremality. Finally we comment briefly on the implications of our results for the information loss problem.

“…In the full low-energy string effective action, the dilaton and the axion are non-minimally coupled scalars, though, and the existence of black-hole solutions with regular horizons in theories with non-minimally coupled scalars is known [26,27]. In these solutions, the scalar (dilaton) charge is identical to a certain fixed combinations of the other, conserved, charges:…”

We study the transformation under the full String Theory duality group of the observable charges (including mass, angular momentum, NUT charge, electric, magnetic and different scalar charges) of four dimensional pointlike objects whose asymptotic behavior constitutes a subclass closed under duality.We find that those charges fall into two complex four-dimensional representations of the duality group. T duality (including Buscher's transformations) has an O(1, 2) action on them and S duality a U (1) action. The generalized Bogomol'nyi bound is an U (2, 2)-invariant built out of one representations while the other representation (which includes the angular momentum) never appear in it. The bound is manifestly duality-invariant.Consistency between T duality and supersymmetry seems to require that primary scalar hair is included in the generalized Bogomol'nyi bound. We also find that all known four-dimensional supersymmetric massless black holes are the T duals in the time direction of the usual massive supersymmetric black holes. Non-extreme massless "black holes" can be found as the T duals of the non-extreme black holes. All of them have primary scalar hair and naked singularities.
