Comparison of charged lepton and neutrino deep-inelastic scattering. Parity violation;

QCD corrections.

The Drell-Yan Process. Comparison with Double Pomeron Exchange.

Jet production and fragmentation. Direct Photon Production.

Anomalies. "EMC" nuclear effect and spin structure of the nucleon.

Introduction to String model of fragmentation. Artru-Menessier model and the Lund Model.
