Goal of the course | Advanced course for graduate and advanced undergraduate students. Normally it follows the course “Elementary Particles and Forces” (Ph422) of the undergraduate program and its purpose is to familiarize the student with the techniques of Quantum Field Theory, the computation of particle processes and the deeper understanding of High Energy Physics. |

Syllabus | The Schroedinger and Heisenberg pictures. Noether theorem. Lorentz transformations. Poincare algebra and its representations. Quantization of real and complex scalar fields. 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. |
