Gravity as a Double Copy of Gauge Theory

Explore the fascinating connection between gravity and gauge theory in this 49-minute conference talk by Henrik Johansson at BIMSA. Delve into the concept of gravitational double copy and the gauge-theory duality between color and kinematics. Discover how Yang-Mills scattering amplitudes can be used to derive gravitational processes, enabling quantum computations of multiloop amplitudes for graviton scattering and facilitating the study of ultraviolet properties. Learn about the web of gravitational theories constructed through scattering amplitudes using the double copy framework. Examine how classical general relativity can be approached from an S-matrix perspective, providing insights into gravitational wave observables from astrophysical sources through the application of the double copy technique.
