[Colloquium] From Quantum Scattering Amplitudes to Gravitational Waves

Colloquium with Zvi Bern  (UCLA)

Title: From Quantum Scattering Amplitudes to Gravitational Waves

Abstract: In this colloquium, I will introduce key concepts from the modern
theory of quantum scattering amplitudes.  I will then present examples
showing how these ideas are applied to a range of topics, including
collider physics, the relationship between gravity and the other
fundamental forces in the framework of perturbation theory and
fundamental issue for quantum gravity and its supersymmetric
counterparts.  I will also explain recent developments showing that a
quantum description of gravity is useful as a starting point for
obtaining state-of-the-art precision predictions for binary black
holes and other compact astrophysical objects in the context of
gravitational-wave physics.
