Gauge Theories,In these lectures, an introduction to the unified gauge theories, of weak and electromagnetic interactions, is given. Strong interactions are treated only briefly; they constitute the theme of Professor Nachtmann’s lectures.

欢笑

Parton Models,In these lectures we will describe the concept and application of the naive parton model for hadrons invented in the late sixties 1). This model has been extremely successful in comparison with experiment and we will mention some of its successes later on.

Asymptotic Freedom Infrared Instability,Electrons and. nucleons bound in solids, molecules, atoms, nuclei… can be isolated from the bound system by a finite ionization (- or breakup) energy.

Drell-Yan Versus Experiment,f dilepton production. As we will see, lepton pair measurements provide a way of testing various ideas about the distribution of quarks inside the hadrons, and new results from the CERN Intersecting Storage Rings (ISR) will be used to test, in particular, the prediction of scaling and the connection with lepton deep inelastic scattering.

Topless Model for Grand Unification,vanishing gauge coupling. A global SU(4) subgroup which may survive the spontaneous symmetry breaking leads to mass relations. The weak decays of b and h quarks can proceed through non-diagonal neutral currents providing for a specifice signature. The weak mixing angle is in accord with experiments.
