Advanced Topics in the Theory of Scattering Amplitudes

This course provides an introduction to advanced methods used to study multiloop scattering amplitudes in Quantum Field Theory. A rough program will be:

  1. Generalised unitarity for one-loop calculations
  2. Rational terms versus cut-constructible parts
  3. Analytic structure of multiloop Feynman integrals, Landau equations
  4. Differential equations for multiloop Feynman integrals
  5. General properties of (Chen) iterated integrals
  6. Multiple polylogarithms, functional relations and the symbol map
  7. Modern ideas on Feynman integrals and general complex hyper-surfaces, the elliptic case

Depending on the interests of the participants, the program could be slightly adapted during the semester.
