Scattering Amplitudes in Quantum Field Theory

This course provides an introduction to modern methods in perturbative Quantum Field Theory, which find their primary application in high-energy physics. A (rough) program of the course will be:

  1. Representations of the Lorentz and Poincare group, little group and spinor representations 
  2. Spinor helicity formalism for Scattering Amplitudes 
  3. Tree-Level amplitudes, color decomposition and primitive amplitudes,
  4. Recursion techniques (BCFW) 
  5. Loop amplitudes and treatment of UV and IR divergences in dimensional regularization 
  6. Optical theorem, dispersion relations and the analytic structure of scattering amplitudes 
  7. Introduction to Generalized unitarity for one-loop scattering amplitudes (Not subject of final examination)

Lecture Notes

Hand-written notes for the lectures will be uploaded week by week
