Description
I will introduce several key concepts from the
modern theory of quantum scattering amplitudes. These ideas have found
wide-ranging applications, including in collider physics,
supersymmetric gauge theory, supergravity, and gravitational-wave physics. I will show that, within
perturbation theory, gauge theories of the type used in collider
physics are directly connected to theories of gravity, including
Einstein’s general relativity, via a construction known as the double copy
As a particularly recent development, I
will explain how this understanding of gravity provides a
useful starting point for obtaining state-of-the-art precision
predictions for binary black holes and other compact astrophysical
systems in the context of gravitational-wave physics.
