Synopsis:

This lecture is oriented to provide basic applications of quantum chromodynamicks that corresponds to understanding of the dynamics of processes in particle physics at high energies on proton and nuclear targets that are currently measured by experiments at RHIC and LHC colliders. Complementary informations to lectures of Basics of quantum chromodynamics will be provided.

Requirements:

Knowledge of quantum field theory and basics of quantum chromodynamics

Syllabus of lectures:

1. Basics of theory of strong interactions - QCD Lagrangian and symmetries, QCD versus QED, asymptotic freedom, chiral symmetry breaking, quark confinement, evidence for colored quarks

2. Color transparency ? quasi-elastic scattering on nuclei, diffractive electroproduction of vector mesons

3. Hadronization of colored charges

4. DIS - Bjorken scaling and parton model, scaling violation and DGLAP evolution equation, factorization theorem

5. BFKL formalism

6. GLR-MQ evolution equation and saturation

7. Color dipole formalism and DIS at small x - KST model, GBW model, GBW model with DGLAP equation and dipole evolution

8. Production of Drell-Yan pairs and direct photons - parton description,color dipole approach description

9. Diffraction - diffraction in non-abelian theories, quantum mechanics of diffraction, diffractive DIS, diffractive Drell-Yan, diffractive Higgs boson production

10. Quark and gluon shadowing, Cronin effect and nuclear broadening

11. Quenching of high-pT hadrons: Energy loss vs Color transparency
