Quantum Chromodynamics
After a brief historical review of the emergence of QCD as the quantum field theory of strong interactions, the basic notions of colour and gauge invariance are introduced leading to the QCD Lagrangian. The second lecture is devoted to perturbative QCD, from tree-level processes to higher-order corrections in renormalized perturbation theory, including jet production in e + e − annihilation , h...
متن کاملQuantum Chromodynamics *
The classical Lagrangian of chromodynamics, its quantization in the perturbation theory framework, and renormalization form the subject of these lectures. Symmetries of the theory are discussed. The dependence of the coupling constant αs on the renormalization scale μ is considered in detail.
متن کاملQuantum ChromoDynamics
These lectures on QCD stress the theoretical elements that underlie a wide range of phenomenological studies, particularly gauge invariance, renormalization, factorization and infrared safety. The three parts cover the basics of QCD, QCD at tree level and higher order corrections. Lectures given at the 2004 European School of High-Energy Physics, St. Feliu de Guı́xols, Barcelona, Spain, 30 May –...
متن کاملAspects of Quantum Chromodynamics *
These lectures provide an overview of Quantum Chromodynamics (QCD), the SU (3) C gauge theory of the strong interactions. The running of the strong coupling and the associated property of Asymptotic Freedom are analyzed. Some selected experimental tests and the present knowledge of αs and the quark masses are briefly summarized. A short description of the QCD flavour symmetries and the dynamica...

ACKNOWLEDGEMENT Before beginning, I wish to acknowledge the invaluable and generous help of Marvin Weinstein in introducing me to much of the material covered in these lectures. While there are many shortcomings of these n0tF.s , they are not to be blamed on him; they would have been much poorer without his help and insights. .
