Learning outcomes
The course provides advanced knowledge of the theory of the Standard Model of elementary particle. The student will get acquainted with the properties and features of our current description of the fundamental particles and their interactions. Motivated by its theoretical limitations as well as by the current experimental observations, the students will then be exposed to the most common avenues towards extending the Standard Model and searching for new physics in high-energy experiments
Course contents
The course provides advanced knowledge of the theory of the Standard Model of elementary particles, with open questions from a theoretical and phenomenological perspective. The course is divided into three parts.
The first part is on precision Standard Model physics:
Lagrangian of the SM. Custodial Symmetry and the rho parameter. Linear and non-linear EW symmetry breaking. EW chiral Lagrangian. Unitarity and perturbativity of the SM. Higgs mass bounds: unitarity, triviality and stability. EW precision-observables (EWPO) and renormalisation schemes. Higgs phenomenology: decays and production. Top-quark phenomenology: decays and single and pair production.
The second part is dedicated to effective field theories:
Motivation and basic concepts: top-down and bottom-up approaches, power counting, renormalizability, operator bases, matching. Applications: Fermi Theory, the Standard Model as an Effective Field Theory. Phenomenology and constraints from precision experiments and LHC constraints. EFTs at one loop: matching and RGE running.
The third part places a focus on neutrino physics:
Brief history of neutrinos in the Standard Model. Neutrino oscillations in vacuum and in matter. Current status and open questions for the future. Nature and masses of neutrinos: Majorana and Dirac particles. Origin of neutrino masses beyond the Standard Model. Brief overview of related open problems of the Standard Model: dark matter; the baryon asymmetry and leptogenesis; the flavour puzzle.
Knowledge of the Standard Model Lagrangian and of Quantum Field Theory will be assumed.
