Quantum ChromoDynamics

Abstract

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.

Comments: These lectures, given at the 5th CERN-Latin-American School of High-Energy Physics, Recinto Quirama, Colombia, 15 - 28 Mar 2009, have been withdrawn since they contain only minor modifications to arXiv:hep-ph/0505192 which has been updated
