Quantum Chromodynamics by Gerhard Ecker
Quantum Chromodynamics
Quantum Chromodynamics by Gerhard Ecker
Publisher: arXiv 2006
Number of pages: 48
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. The final two lectures treat various aspects of QCD beyond perturbation theory.
