Parton structure of nucleons and nuclei 1100-3`PSNN
Contents
--------------
1. Introduction: units, magnitudes, four-vectors, fundamental interactions, experimental methods. Reaction amplitude and cross section; electromagnetic interaction, form factor; Feynman diagrams in QED, time- and space-like interactions; intermediate bosons.
2. Nucleon structure research centres: past (SLAC, DESY, FNAL) and present (CERN, BNL, JLAB). Fixed-target and collider experiments and their research programmes. Observables.
3. Elastic scattering of electrons off atomic nuclei and nucleons, elastic form factor and charge distribution, Rosenbluth plot. JLAB revolution.
4. Deep inelastic scatering of charged and neutral leptons off protons, quark-parton model, nucleon structure functions, scaling and its breaking, parton distributions in the nucleon, QCD-improved parton model, structure functions of bound nucleons. Radiative corrections.
5. Basics of QCD including asymtotic freedom and the running coupling. QCD fits to the data and universal functions of parton distributions in the nucleon, quark fragmentation functions.
6. A new degree of freedom, spin: status of the proton spin puzzle, nucleon spin structure in the quark model, spin-dependent structure functions, experimental methods and results. Transversity.
7. Models of strong interactions: Lund Monte Carlo programs (PYTHIA, LEPTO, AROMA, ...). Radiative corrections and their simulations (RADGEN), detector simulations (GEANT).
8. Special aspects of the deep inelastic scattering: nonperturbative region, Vector Meson Dominance model, low x physics, diffraction.
9. A.o.b. or subjects requested by participants.

Learning outcomes
Experience in using ideas, results, and phenomenology of parton research as well as becoming familiar with public tools (data bases, Monte Carlo programs, parameterisations) available in that field and needed in almost all high energy physics expriments.
Assessment criteria
Examination
-------------------
Idividual, oral
Practical placement
Not foreseen but completion of the course will faciliate adaptation to work in large research groups e.g. at CERN.
