Greybody factors for rotating black holes in four dimensions
We present the wave equation for a minimally coupled scalar field in the background of a rotating four-dimensional black hole that is parametrized by its mass, angular momentum, and four independent U(1) charges. The near horizon structure is identical to the five-dimensional case, and suggestive of an underlying description in string theory that is valid in the general non-extremal case. We ca...
متن کاملGreybody Factors for Black Holes in Four Dimensions: Particles with Spin
We compute the emission spectrum of minimally coupled particles with spin that are Hawking radiated from four dimensional black holes in string theory. For a range of the black hole parameters the result has a product structure that may be interpreted in terms of the respective rightand left-moving thermal correlation functions of an effective string model. For spin-one and spin-two particles a...
متن کاملMicroscopics of Rotating Black Holes : Entropy and Greybody Factors ∗
We review the status of microscopic counting of rotating black hole degrees of freedom. We present two complementary approaches which both utilize the near-horizon geometry and precisely reproduce the Bekenstein Hawking entropy for near-extreme rotating black holes in D=4 and D=5. The first one, proposed by Strominger, is applicable for the Ramond-Ramond sector and relies on the correspondence ...
متن کاملRotating black holes at future colliders: Greybody factors for brane fields
We study theoretical aspects of the rotating black hole production and evaporation in the extra dimension scenarios with TeV scale gravity, within the mass range in which the higher dimensional Kerr solution provides good description. We evaluate the production cross section of black holes taking their angular momenta into account. We find that it becomes larger than the Schwarzschild radius sq...
متن کاملCharged Rotating Black Holes in Odd Dimensions
We consider charged rotating black holes in D = 2N + 1 dimensions, D ≥ 5. While these black holes generically possess N independent angular momenta, associated with N distinct planes of rotation, we here focus on black holes with equal-magnitude angular momenta. The angular dependence can then be treated explicitly, and a system of 5 D-dependent ordinary differential equations is obtained. We s...
