In this paper we investigate open string pair production effects near hyperbolic black holes in AdS 5 . We study the classical dynamics of D3 probe branes in this background and their quantum tunneling rate across the horizon from the inside using a method similar to that of Kraus, Parikh and Wilczek. The hyperbolic black holes can decay through these tunneling events and their lifetime is estimated. The radiated branes move towards the boundary and do not bounce back. Their world-lines do not intersect directly and they do not hit the singularity either, providing a clean scenario for studying the non-adiabatic pair production effects of open strings stretched between them near horizon. We find that there is a well defined parameter regime where there can be significant pair production. This requires the radiated branes to be highly boosted. However, the radiation of such branes still has small back-reaction on the black hole background, though the open string pair production on them can potentially alter the background. We comment on the possible relation of our model and the AMPS paradox. Some issues and future directions are discussed in the end.

“…The configurations described in this paper are solutions to six-dimensional N = (1, 0) supergravity coupled to n T tensor multiplets, with three commuting isometries. Upon dimensional 1 There are some alternative approaches, including the construction of near-extremal microstates using probe antibranes [29,30], investigating string production near black hole horizons [31,32], and investigating the physics of soft particles [33]. However, such approaches lack either the generality or the precision and control that fully-backreacted supergravity solutions offer.…”

We introduce a solvable system of equations that describes non-extremal multicenter solutions to six-dimensional ungauged supergravity coupled to tensor multiplets. The system involves a set of functions on a three-dimensional base metric. We obtain a family of non-extremal axisymmetric solutions that generalize the known multicenter extremal solutions, using a particular base metric that introduces a bolt. We analyze the conditions for regularity, and in doing so we show that this family does not include solutions that contain an extremal black hole and a smooth bolt. We determine the constraints that are necessary to obtain smooth horizonless solutions involving a bolt and an arbitrary number of Gibbons-Hawking centers.

“…Highly excited strings (HES) are responsible for numerous miraculous properties of string perturbation theory, they play a central role in ensuring the absence of ultraviolet (UV) divergences and are a crucial ingredient in regarding string theory as a theory of quantum gravity. A fundamental driving force underlying much of the recent flourish of interest [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] is that a detailed and careful study of HES (in addition possibly to branes and other solitons in string theory) will likely reveal previously unforeseen features of quantum gravity. For example, in reference to quantum black holes (BH), both in terms of microstates out of which the black hole interior is constructed [19][20][21][22][23] (usually with some additional ingredients), and in terms of (possibly non-local) structure at the black hole horizon due to string effects [5,6,[9][10][11][12]18], building on earlier ideas [19,[24][25][26][27][28][29][30][31][32][33], with possible implications for the black hole information paradox.…”

Highly excited strings I: Generating function

2017

View full text Add to dashboard Cite

This is the first of a series of detailed papers on string amplitudes with highly excited strings (HES). In the present paper we construct a generating function for string amplitudes with generic HES vertex operators using a fixed-loop momentum formalism. We generalise the proof of the chiral splitting theorem of D'Hoker and Phong to string amplitudes with arbitrary HES vertex operators (with generic KK and winding charges, polarisation tensors and oscillators) in general toroidal compactifications E = R D−1,1 × T Dcr−D (with generic constant Kähler and complex structure target space moduli, background Kaluza-Klein (KK) gauge fields and torsion). We adopt a novel approach that does not rely on a "reverse engineering" method to make explicit the loop momenta, thus avoiding a certain ambiguity pointed out in a recent paper by Sen, while also keeping the genus of the worldsheet generic. This approach will also be useful in discussions of quantum gravity and in particular in relation to black holes in string theory, non-locality and breakdown of local effective field theory, as well as in discussions of cosmic superstrings and their phenomenological relevance. We also discuss the manifestation of wave/particle (or rather wave/string) duality in string theory.
