Titre |
From Scattering Amplitudes to Gravitational Waves |
|
Résumé |
The remarkable detection of gravitational waves by the LIGO/Virgo collaboration
has opened a new window into the cosmos. In this colloquium we explain how
particle theorists can help out with state-of-the-art calculations directly
relevant for gravitational-wave emission from compact astrophysical objects. The
past decade has seen enormous advances in our ability to compute quantum
scattering amplitudes making seemingly impossible calculations tractable. These
advances include ideas such as the duality between color and kinematics, double-
copy relations and generalized unitarity. After introducing these concepts we
explain how these ideas can be transferred to the binary black hole inspiral
problem. |
