Radiation reaction for spinning black-hole scattering

چکیده
Starting from the leading soft term of 5-point amplitude, involving a graviton and two Kerr black holes, that factorises into product elastic amplitude without factor, we compute infrared divergent contribution to imaginary part two-loop eikonal. Then, using analyticity crossing symmetry, determine radiative real eikonal it deflection angle for spins aligned orbital angular momentum, loss momentum zero frequency limit energy spectrum any spin orientation. For one find perfect agreement with recent results obtained supersymmetric worldline formalism.

Spinning Black Hole Energetics
We discuss black hole energy processes that could serve as the mechanism for relativistic jets. The energy-extraction process of Roger Penrose is presented. The existence of the negative energy region is derived from the extreme Kerr metric. Theoretical limits on the efficiency of the process are discussed. An analogous process for a Kerr-Newman hole is presented. The Blandford-Znajek process i...
متن کاملEffect of gravitational radiation reaction on circular orbits around a spinning black hole.
The effect of gravitational radiation reaction on circular orbits around a spinning (Kerr) black hole is computed to leading order in S (the magnitude of the spin angular momentum of the hole) and in the strength of gravity M/r (where M is the mass of the black hole, r is the orbital radius, and G = c = 1). The radiation reaction makes the orbit shrink but leaves it circular, and drives the orb...
متن کاملSpinning Particle, Rotating Black Hole and Twistor-string * Rotating Black Hole as Spinning Particle
Structure of the spinning particle based on the rotating black hole solution is considered. It has gyromagnetic ratio g = 2 and a nontriv-ial twistorial and stringy systems. The mass and spin appear from excitations of the Kerr circular string, while the Dirac equation describes excitations of an axial stringy system which is responsible for scattering. Complex Kerr geometry contains an open tw...
متن کاملTowards black hole scattering
We study black holes in three-dimensional Chern-Simons gravity with a negative cosmological constant. In particular, we identify how the Chern-Simons interactions between a scattering particle and a black hole project the particle wavefunction onto a wavefunction in the black hole background. We also analyze the set of space-times that should be allowed in the theory and the way in which bounda...
متن کاملBack Reaction of Gravitational Radiation on the Schwarzschild Black Hole
We address some of the issues that appear in the study of back reaction in Schwarzschild backgrounds. Our main object is the effective energymomentum tensor (EEMT) of gravitational perturbations. It is commonly held that only asymptotically flat or radiation gauges can be employed for these purposes. We show that the traditional Regge-Wheeler gauge for the perturbations of the Schwarszchild met...
