Baryons

Abstract

In this chapter we will discuss the production and decay of those baryons which are made up of u-, d- and s-quarks. It will be shown that the spin of the baryons is equal to the vector sum of the spins of the three constituent quarks and that the magnetic moments and the masses calculated with this assumption excellently agree with the experimental results. Polarized deep-inelastic scattering experiments are addressed that revealed the surprising result that the fraction of the nucleon’s spin which can be attributed to the current-quark spins may be small. Finally, semileptonic weak baryon decays are discussed in some detail.
