The Quark Model

Concepts of Elementary Particle Physics, 2019
Abstract 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.

Quark model and the triton

Physical Review C, 1988
The Virginia NN potential, which is based on an effective quark interchange mechanism at medium and long distances and is supplemented by a six-quark core potential with a P-matrix type parametrization, is used for calculating the triton binding energy.

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.

Heavy-quark mesons in a relativistic quark model

Physical Review D, 1991
The Coulomb-gauge QCD Hamiltonian, augmented by a term which produces linear, scalar confinement is used to generate kernels for the bound-state amplitudes and eigenvalues of heavy quarkonium. The model generates all the correct perturbative physics up to order {alpha}{sub {ital s}}{sup 4} and is applied to the {ital c{bar c}} and {ital b{bar b ...
