Explore the intricate connections between chord diagrams, the global Schwinger formula, and ϕp amplitudes in this 58-minute conference talk delivered by K. Yeats from the University of Waterloo. Delve into advanced mathematical physics concepts as part of "The Amplituhedron: Structure, Combinatorics, and Positive Geometry" conference series organized by NCCR SwissMAP. Examine how chord diagrams serve as combinatorial tools in quantum field theory calculations, understand the application of the global Schwinger formula in amplitude computations, and investigate the properties of ϕp amplitudes within the broader context of positive geometry and amplituhedron theory. Gain insights into cutting-edge research at the intersection of combinatorics, algebraic geometry, and theoretical physics, particularly focusing on how these mathematical structures contribute to our understanding of scattering amplitudes and their geometric representations.
