Syllabus
Prerequisites: Basic knowledge on quantum mechanics, relativity, nuclear and subnuclear physics. Quantum field theory and Feynman graphs. Interaction of radiation and particles with matter.
Examination methods: A written test, including numerical execises and multi-answer questions. An oral test: the student can choose to discuss in detail the contents of a published article (and all the issues pertinent to it) among a set of those proposed during the lessons, or to be questioned on all the subjects discussed during the course.
Course unit contents: A brief reminder of basic concepts: symmetries, conservation laws, quantum numbers and elementary particle classification. Lifetime, resonances and Breit Wigner distribution.
QED: brief reminder of theoretical foundation, tree levels processes and loop diagrams. The running coupling constant. Experimental tests: success and open issues.
Weak interactions of leptons and quarks. Fermi constant(Gf), weak gauge bosons, relation between Gf and MW. Muon and tau decays: lepton universality. P,C violation in charged and weak currents. Nuclei, baryon and meson weak decays: "helicity suppression". Neutrino scattering. Spontaneous symmetry breaking and the Higgs boson. Measurements at LEP and at the LHC. Status and perspectives.
QCD. Hadron spectroscopy. ee annihilation to hadrons. Deep inelastic scattering of electrons and neutrinos; nucleon structure functions.
Hadron flavour Physics. The CKM matrix. Flavour oscillations and CP violation.
