Prerequisites:

Basic knowledge on quantum mechanics, relativity, nuclear and subnuclear physics. Quantum field theory and Feynman graphs. Interaction of radiation and particles with matter. 
Target skills and knowledge:

Experimental foundations of the present understanding of the fundamental interactions. Basic experimental techniques applied in particle physics. Phenomenology of the Standard Model:fundamental interactions, fundamental particle classification, hadron spectroscopy. Computation or estimate of decay widths and cross sections for strong, electromagnetic and weak interactions.Open issues and future prospects. 
Examination methods:

A written test, including numerical execises and multianswer 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. 
Assessment criteria:

written test: 10 points (minimum mark for success : 5 points)
discussion: 20 points (minimum mark : 10)
sum of the two marks must exceed 17 points 
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. 
Planned learning activities and teaching methods:

Traditional lessons with chalk and blackboard for about 80% of the time. Theory and exercises. Use of slides mostly to describe experiments. 
Additional notes about suggested reading:

I invite students to take private notes during the lessons. Most of the arguments presented are discussed at length in the suggested textbooks: integration will be provided when needed. Copies of the slides are available on moodle.
