Deuteron photodisintegration and quark models
Physical Review C, 1990We have examined the behavior of the forward-to-backward ratio {ital R} of the cross section for the {sup 2}H({gamma},{ital p}){ital n} reaction. The data show a weak dependence of {ital R} on the photon energy and group around a value of 1.5 which agrees with the prediction of a simple quark model.

Ideal quarks and mesons in the relativistic quark model
Physical Review C, 1994We propose a microscopic theory for interacting mesons and ideal quarks in the relativistic quark model using the time-dependent mean-field theory technique. For simplicity we examined the Nambu--Jona-Lasinio model. The dynamical chiral-symmetry breaking leads to a zero-frequency mode (pion) due to the restoration of chiral symmetry.

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 ...

The scope of a relativistically covariant constituent quark model of baryons based on the BetheSalpeter equation in instantaneous approximation is illustrated by a discussion of various baryon resonance observables such as static electromagnetic moments including a novel calculational procedure form factors and helicity amplitudes, semileptonic decays ...

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.
