16 Lectures Dr. D. Maitre
The course will develop techniques for computing scattering processes at tree
level and one-loop.
The first part of the course builds on the Introduction to Quantum
Field Theory course and is concerned with the application of Feynman rules to
elementary scattering processes. The second part introduces Bremsstrahlung and
loop corrections and describes how to handle the infrared and ultraviolet
divergences that are present.
Outline of course
- QED at tree level:
Application of Feynman rules for tree-level processes in QED, gamma-matrix algebra, traceology, polarization sums, unpolarized cross sections, crossing symmetry.
- QED at one loop
UV singularities, dimensional regularization, techniques for evaluation of one-loop integrals, renormalization, Lamb shift, g-2, Ward identities, IR singularities.
