Quantum Chromodynamics (QCD)
This is a collection of links to video lectures on quantum chromodynamics (QCD) from CERN - Introduction to QCD, QCD Phenomenology at High Energy, Perturbative QCD, etc.
| Video/text | Perturbative QCD |
| Description | By Aude Gehrmann-De Ridder, 2013. Perturbative QCD is the general theoretical framework for describing hard scattering processes yielding multiparticle production at hadron colliders. In these lectures, we shall introduce fundamental features of perturbative QCD and describe its application to several high energy collider processes. ... |
| Video/text | Beyond Feynman Diagrams |
| Description | By Lance Dixon, 2013. For decades the central theoretical tool for computing scattering amplitudes has been the Feynman diagram. However, Feynman diagrams are just too slow, even on fast computers, to be able to go beyond the leading order in QCD, for complicated events with many jets of hadrons in the final state. ... |
| Video/text | QCD for Postgraduates |
| Description | By Giulia Zanderighi, 2010. Modern QCD - Lecture 1 Starting from the QCD Lagrangian we will revisit some basic QCD concepts and derive fundamental properties like gauge invariance and isospin symmetry and will discuss the Feynman rules of the theory. ... |
| Video | QCD Phenomenology at High Energy |
| Description | By Bryan Webber, 2008. These lectures will review the foundations and limitations of perturbative QCD and its application to high-energy processes, including jet production and fragmentation, deep inelastic scattering, and heavy quark and Higgs boson production. ... |
| Video/text | QCD and High-energy nuclear collisions |
| Description | By D. Kharzeev, 2007. Six years ago, Relativistic Heavy Ion Collider at Brookhaven started colliding heavy nuclei at record center-of-mass energies of up to 200 GeV/nucleon. Very soon, the Large Hadron Collider at CERN will push the energy of the ions to an astounding 5 TeV/nucleon. What can be learnt from the experiments at these machines? ... |
| Video/text | QCD: are we ready for the LHC? |
| Description | By S. Frixione, 2006. In these lectures, I'll introduce basic concepts in QCD, and present techniques based on perturbation theory, such as fixed-order and resummed computations, and Monte Carlo simulations. I'll discuss applications of these techniques to hadron-hadron processes, concentrating on recent trends in perturbative QCD aimed at improving our understanding of LHC phenomenology. ... |
| Video | Introduction to QCD |
| Description | By B. Webber, 2003. The emphasis of the lectures will be on QCD phenomenology at high energy. The main topics of the five lectures will be: 1) Basics of QCD. 2) e+e- & parton branching. 3) Evolution equations. 4) Jet fragmentation. 5) DIS & hadron-hadron processes. ... |
| Video | QCD |
| Description | By B. Webber, 1999. Basic Properties of QCD: the Lagrangian, the running coupling, asymptotic freedom and colour confinement. Examples of perturbative calculations in electron-positron physics (total cross sections and event) ... |
| Video | Introduction to QCD |
| Description | By Stefano Catani, 1998. The lectures introduce to some basic aspects and concepts of perturbative QCD : running coupling and asymptotic freedom, the parton model, infrared divergences and the factorization theorem, parton, densities and parton evolution, colour coherence. Applications to e+e-annihilation, deep inelastic lepton-nucleon scattering and hadron-hadron collisions are discussed. ... |
| Video | Quantum Chromodynamics |
| Description | By Michelangelo Mangano, 1997. 1. Gauge invariance and Feynman rules for QCD. 2. Renormalization, running coupling and operator product expansion. 3. QCD in e+e- collisions: from quarks and gluons to hadrons; R, jets and shape variables. 4. QCD in lepton-hadron collisions: DIS structure functions, sum rules and parton evolution. 5.

| Video | Quantum Chromodynamics |
| Description | By Matthias Neubert, 1996. Quantum chromodynamics (QCD) is the fundamental theory of the strong interactions. It is local, non-abelian gauge theory describing the interactions between quarks and gluons, the constituents of hadrons. In these lectures, the basic concepts and ph will be introduced in a pedagogical way. ... |
