Synopsis:

The goal of these lectures is to acquire knowledge about basic principles of strong interaction starting from the

constituent quark model and SU(3) flavour symmetry, studies of nucleon structure in deep inelastic scattering of leptons on nucleons and parton model to basics of Quantum Chromodynamics and its practical applications in the context of current experiments in high energy physics and physics of ultra-relativistic heavy-ion collisions.

Requirements:

Knowledge of basic course of physics, knowledge of quantum mechanics and quantum field theory

Syllabus of lectures:

1. Spectrum of hadrons, basics of group theory

2. Non-relativistic model of constituent quarks, SU(3) flavour and SU(3)xSU(2) flavour-spin symmetry

3. Elastic, inelastic and deep inelastic lepton-nucleon scattering

4. Parton model (parton distribution functions, sum rules, universality of structure functions, annihilation of electrons and positrons at high energies, Drell-Yan production of dileptons)

5. Lagrangian of Quantum Chromodynamics (QCD), differences between quantum electrodynamics and chromodynamics, QCD running coupling constant and its measurements, asymptotic freedom, perturbative QCD

6. Feynman rules in QCD and calculation of basic processes: quark-quark, quark-gluon and gluon-gluon scattering

7. QCD improved parton model (WWA approximation, branching functions, DGLAP evolution equations)

8. Jets (jet reconstruction algorithms, jet measurements)

9. Monte-Carlo generators in particle physics and hadronization

10. Quark confinement, chiral symmetry, quark-gluon plasma, lattice QCD calculations
