TITLE  The EOB model for black hole scattering and its numerical analysis
ABSTRACT

  Most sources of gravitational waves detected in LIGO and Virgo are modeled in the post-Newtonian approximation where the motion is slow and the gravitational field is weak. Recently, a post-Minkowskian approximation for relativistic unbound orbits has been studied and leading to improved effective-one-body (EOB) modeling. We improve the EOB model by using the gravitational scattering angle studies and compare the analytical result with numerical results obtained from numerical simulations.
