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. |
