HET Brown Bag Seminar | Landau Singularities and the Amplituhedron
Marcus Spradlin (Brown)
Modern methods for computing scattering amplitudes in quantum field theory get enormous mileage out of knowledge (or assumed knowledge) of their singularity structure. I will demonstrate how, in the very special case of supersymmetric Yang-Mills theory, all information about this singularity structure can (in principle) be derived via combinatorial geometry problems using the amplituhedron, providing thereby the basic input to the "amplitude bootstrap" program.
