Scattering amplitudes are a key arena where quantum field theory directly confronts experiment and where a precise understanding can be crucial for identifying Beyond Standard Model signals at particle colliders such as the LHC. At the same time, scattering amplitudes have revealed beautiful and intriguing mathematical structures and patterns that suggest that our fundamental understanding of quantum field theory is far from complete. The study of scattering amplitudes has been a growing area of research over the past decade, with applications ranging from precision calculations for the LHC, new approaches to gauge and gravity theories, LIGO physics, to Amplituhedron and exciting connections to geometry and combinatorics.
