Advanced QCD Concepts at Low Energies

Dr. Matthias Jamin (IFAE, Barcelona)

The aim of this lecture is to introduce advanced QCD concepts which are useful to apply QCD at lower energies. After recapitulating basic perturbative tools like regularisation, renormalisation and the renormalisation group, more advanced methods will be introduced and discussed. These include dispersion relations, the operator product expansion (OPE), QCD sum rules, flavour symmetry, chiral symmetry, chiral perturbation theory, anomalies and the strong CP problem. With the aid of the OPE, the large-order behaviour of the perturbative series and renormalons will also be investigated.
