The quark model [PDF]

Reports on Progress in Physics, 1978
The quark model is reviewed in a version which includes three colours and at least five quark flavours. Methods are discussed which are applicable to any number of flavours, provided the underlying symmetry is SU(n). The relation between quark bound states and hadron spectroscopy is discussed, and sum rules are given for baryon magnetic moments and ...

Quark-Quark Interaction and the Nonrelativistic Quark Model

Physical Review Letters, 1980
This Letter demonstrates that the nonrelativistic approximation breaks down for the lighter hadrons with the conventional $\mathrm{qq}$ one-gluon exchnage potential. This is mainly due to the Coulomb and the short-range hyperfine interactions. To overcome this difficulty, some phenomenological interactions with a long-range spin dependence are proposed.

The Quark Model

Concepts of Elementary Particle Physics, 2019
This chapter presents the quark model of hadrons. It discusses the quark description of the quark antiquark systems of c and b quarks. It then describes the structure of the lightest mesons and baryons as bound states of u, d, and s quarks.
