Fixed scalar greybody factors in five and four dimensions
Igor R. Klebanov, Michael Krasnitz
We perform the classical gravity calculations of the fixed scalar absorption cross-sections by D=5 black holes with three charges and by D=4 black holes with four charges. We obtai…
Scattering of Strings from D-branes
Akikazu Hashimoto, Igor Klebanov
We review a number of perturbative calculations describing the interactions of D-branes with massless elementary string states. The form factors for the scattering of closed string…
Absorption of Fixed scalars and the D-brane Approach to Black Holes
C. G. Callan, S. S. Gubser, I. R. Klebanov +1
We calculate the emission and absorption rates of fixed scalars by the near-extremal five-dimensional black holes that have recently been modeled using intersecting D-branes. We fi…
Four-dimensional greybody factors and the effective string
S. S. Gubser, I. R. Klebanov
Recently Maldacena and Strominger found that the calculation of greybody factors for black holes carrying three U(1) charges gives striking new evidence for their description…
Emission of charged particles from four- and five-dimensional black holes
Steven S. Gubser, Igor R. Klebanov
Recently Das and Mathur found that the leading order Hawking emission rate of neutral scalars by near-extremal black holes is exactly reproduced by a string theoretic model i…
Near-extremal black hole entropy and fluctuating 3-branes
I. R. Klebanov, A. A. Tseytlin
We discuss the known microscopic interpretations of the Bekenstein-Hawking entropy for configurations of intersecting M-branes. In some cases the entropy scales as that of a massle…
