### Event details

Cut Feynman integrals have long been appreciated as a tool describing discontinuities of scattering amplitudes or Feynman diagrams in terms of simpler expressions. Focusing on one-loop diagrams, I will discuss the interpretation of cut integrals as residues, connections with Landau singularities, and some remarkable relations among different cut integrals.

#### Event resources

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
