We discuss the perturbative description of QCD - the theory of the strong interactions.

Main chapters:

the QCD Langrangian

UV renormalization of QCD Renormalization group Physical examples:

electron-positron annihilation into jets (leading order, next-to-leading order and the dipole method, cut diagrams, helicity formalism)

deep inelastic scattering (factorization theorem)

hadron-hadron scattering
