The Basic Principles of Quantum Chromodynamics

Part of the Texts and Monographs in Physics book series (TMP)


We have learnt in the previous chapters that hadrons can be understood as bound states of constituents called partons. We found that the partons that take part in the electromagnetic and weak interactions have spin 1/2 and carry the internal quantum numbers of the quarks; in particular, they carry fractional charges. We have further discovered that the quarks possess an additional degree of freedom, the color, and that experiments demand the existence of flavor-neutral partons, gluons, in the nucleon. The question now arises as to what forces are responsible for holding the partons together in the hadrons.
