چکیده
A bstract We compute the scattering amplitude for classical black-hole to third order in Post-Minkowskian expansion, keeping all terms needed derive angle that from eikonal formalism. Our results confirm a conjectured relation between real and imaginary parts of by Di Vecchia, Heissenberg, Russo, Veneziano, are agreement with recent computation Damour based on radiation reaction general relativity.

Resonance scattering at third-order exceptional points
We analyze scattering cross sections at and near third-order exceptional points (EP3), i.e., points in physical parameter space where three energies and eigenfunctions coincide. At an EP3, the Green’s function contains a pole of third order, in addition to poles of second and first order. We show that the interference of the three pole terms produces a rich variety of line shapes at the excepti...
متن کاملGravitational radiation from inspiralling compact binaries completed at the third post-Newtonian order.
The gravitational radiation from point particle binaries is computed at the third post-Newtonian (3PN) approximation of general relativity. Three previously introduced ambiguity parameters, coming from the Hadamard self-field regularization of the 3PN source-type mass quadrupole moment, are consistently determined by means of dimensional regularization, and proved to have the values xi=-9871/92...
متن کاملStructure of the Semi-Classical Amplitude for General Scattering Relations
We consider scattering by general compactly supported semi-classical perturbations of the Euclidean Laplace-Beltrami operator. We show that if the suitably cut-off resolvent of the Hamiltonian quantizes a Lagrangian relation on the product cotangent bundle, the scattering amplitude quantizes the natural scattering relation. In the case when the resolvent is tempered, which is true under some no...
متن کاملScattering of Gravitational Radiation Second Order Moments of the Wave Amplitude
Gravitational radiation that propagates through an inhomogeneous mass distribution is subject to random gravitational lensing, or scattering, causing variations in the wave amplitude and temporal smearing of the signal. A statistical theory is constructed to treat these effects. The statistical properties of the wave amplitude variations are a direct probe of the power spectrum of the mass dist...
متن کاملSpin induced multipole moments for the gravitational wave amplitude from binary inspirals to 2.5 Post-Newtonian order
Direct detection of gravitational waves (GWs) is an international experimental effort which includes the earth-based LIGO/Virgo detectors [1] and the future space-based mission eLISA [2]. Among the most promising sources for these detectors are coalescing compact binary systems, whose dynamics can be studied using Post-Newtonian methods for the inspiral phase and numerical simulations for the m...
