Inclusive Decays of Heavy Flavours

Part of the The Subnuclear Series book series (SUS, volume 21)


The study of weak decays of heavy flavoured particles is important as a source of information on many interesting aspects of the SU(3) ⊗ SU(2) ⊗ U(1) standard theory. Strong and electroweak effects all contribute to the determination of the decay properties. Much light can be shed on important new and old problems such as the understanding of parton dynamics, the riddle of non-leptonic weak decays of strange particles, and the determination of fundamental parameters in the theory such as the K-M mixing angles. The inclusive (semileptonic and total) decay rates are especially important in that they are the simplest and imply the least amount of model dependency. Many interesting problems are already met at this level, some of them not yet clarified, so that we shall concentrate on inclusive rates in this lecture.
