TVI/TMP-TF1: Introduction to Scattering Amplitudes in Gauge Theories – Overview


About the lecture

Time and place

Tuesday 10:00 - 12:00 c.t. in A348
Wednesday 10:00 - 12:00 c.t. in A348

In this course modern developments and techniques for scattering amplitudes in gauge theories will be discussed. The main topics will be tree- and loop-level amplitudes in massless (non supersymmetric and maximally supersymmetric) gauge theories.



The material covered will include

  • spinor helicity formalism
  • on-shell recursion relations
  • generalized unitarity method
  • N=4 SYM on-shell superspace and superamplitudes
  • Wilson loop/scattering amplitude duality
  • (super)conformal and dual (super)conformal symmetries.
