PHYS 653, Theoretical Physics Track: Quantum Electrodynamics

This PhD course deals with quantum electrodynamics (QED), which is one of the most successful and most accurate theories known in physics.  QED is the quantum field theory of electrons, positrons, and photons. Application of Feynman rules for tree-level processes in QED, Dirac algebra, polarisation sums, unpolarised cross sections, and decay rates. Renormalisation,  Divergences in Feynman integrals, Higher Order Corrections, Counter terms, Dimensional Regularisation, and one loop renormalization.
