Landau discriminants

Abstract Scattering amplitudes in quantum field theories have intricate analytic properties as functions of the energies and momenta of the scattered particles.In perturbation theory, their singularities are governed by a set of nonlinear polynomial equations, known as Landau equations, for each individual Feynman diagram.The singularity locus of t
