Particles and Antiparticles (reminder and notation) -- CP symmetry - Gauge Interactions -- Framework of the Electroweak interactions SU(2)L X U(1) - Discussion of Empirical input - Spontaneous symmetry breaking -- The Brout-Englert-Hggs Model - On-Shell Equvalence of the Brout-Englert (renormalieable) and the Higgs (unitary) approaches - W and Z bosons - masses , properties - Predictions vs Inputs of the Standard Model - Quarks and Strong Interactions - SU(3) - Chiral symmetry breaking and the Pion - Quarks and weak Inteactions (Cabibbo-Kobayashi-Maskawa Mixing, absence of flavour changing neutral currents) -- Indirect (radiative corrections) constraints on the Standard Model parameters - CP violation vs gauge interactions : the quark/scalar sector - Anomalies : towards the quantization of charge (if time allows) More advanced chapters: --- The nature of neutrino : Dirac, Majorana particles, mass matrix and CP violation, --- Matter-antimatter asymmetry in the Universe --- Simple variants of the Standard Model, which are real challenges for LHC, (and possible sources of Dark Matter)
Objectives (and/or specific learning outcomes)
-
Presentation of Particle Physics and Fundamental interactions at a state of the art level (arguably our most achieved theory in physics) - At the end of the course, the students should be up to date in the field, and capable to understand the cutting-edge developments, notably the search for the Brout-Englert-Higgs boson at CERN, - The course will aslo provide an indication of possible alternatives to the minimal model, with important implications for future experiments. - It also provides a detailed discussion of neutrino physics, with its current challenges - It provides a fundamental understanding of issues surrounding matter-antimatter asymmetry , including the "defeat of antimatter" in our Universe -
Teaching methods and learning activities
Blackboard course Exercise sessions The examination will also involve a prepared topic chosen by the student
References, bibliography, and recommended reading
