Physics of Strong Interactions

1. Strong Interaction (reminder): hadron structure, quark model

2. Quantum Chromodynamics: QCD lagrangien  -  QCD Feynman rules - vacuum structure - asymptotic freedom - coupling constant runing - quark confinement

3. Annihilation electron-positon - quark-antiquark pair creation- gluon radiation - hadronic jet formation - fragmentation - heavy quarks - hadronic final state structure - alpha_s measurements - QCD gauge structure

4. Electron-proton scattering: proton structure  - parton distributions  - DGLAP evolution

5. Proton-proton interactions: - jet production - QCD factorisation - QCD at the LHC - Drell-Yan processus

Strong interactions are responsible for a wide variety of phenomena, from the coherence of nuclei and hadrons to the wide variety of final states possible in high-energy hadron reactions produced in laboratories (e.g., at the LHC) or by cosmic ray interactions. This course focuses on the phenomenology of strong interactions and addresses the validity of  quantum chromodynamics (QCD) in a perturbative approach. It discusses how hadrons are created, the notion of hadron jets formed from quarks and gluons, the structure of the proton, the evolution of the strong coupling constant, asymptotic freedom, quark confinement in hadrons, and high-energy hadron interactions.
