Conserved charge, antiparticles. The Dirac field. Quantization. Antiparticles. Non-relativistic limit. The gauge principle. Maxwell theory. Quantization and Photons. Spinor and scalar QED. Perturbation theory. Feynman rules for Green’s functions and scattering amplitudes. Scattering cross-section and decay rate of unstable particles. Tree-level processes in relevant models. Quantum corrections. Infinities. Renormalization of a QFT. One-loop renormalization of QED. g-2 of the electron. Introduction to path-integrals. Renormalization and symmetry. Ward-Takahashi identities. The renormalization group. Callan-Symanzik equations. Beta and Gamma functions of QED. |
