Limitations of Fermi Theory,ould — up to now — be classified and understood within this scheme. Nevertheless, as we shall see, the Fermi theory contains severe difficulties and is therefore unsatisfactory. In order to reveal these difficulties we shall discuss first another phenomenon of weak interactions, i.e. the neutral cur

The Salam-Weinberg Theory,ractions, and incorporating charged and neutral currents in a unified way. First we have to learn how to convert a theory involving massless vector bosons into a theory of massive particles, without disturbing the favourable high-energy behaviour of a massless propagator. We shall proceed by discuss

Some Properties of the Salam-Weinberg Theory of Leptons,he neutral current. This made a specific experimental search for these particles possible, to which end it is important to know the possible creation and decay mechanisms. We see immediately that in an electron-positron storage ring it is considerably easier to produce the neutral Z. bosons than the

Semi-Leptonic Interactions of Hadrons,on number . = 0), which always have integer spin. The lightest hadrons, with equal spin (and equal parity), can be arranged in simple multiplets, where two further quantum numbers serve as order criteria: the ., and its third component .., and the ., or alternatively the so-called strong . = . + ..

Unified Gauge Theories,ry treats leptons and quarks on the same footing. However, the fact that leptons carry integer charge while the charge of quarks is 1/3 is needed as a basic input. On the other hand, there are indications that this fact is due to some superior principle, that is a larger symmetry. For example, for l

The Discovery of the Weak Interaction,h binds together atoms and molecules, and gravity, which is the source of binding of objects on an astronomical scale. In order to better understand our modern theory of the weak interaction it is convenient to start with a short review of the history of its discovery.
