Deuteron photodisintegration and quark models

Physical Review C, 1990
We 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.

The Quark Model for Baryons

International Journal of Modern Physics E, 1992
This is an elementary introduction to Quark Models for Baryons. The emphasis is on quick ways of computing matrix elements, especially for axial vector currents and magnetic moments. Various ways of expressing baryon wavefunctions are discussed, especially for the spin-flavor part, and some short explanations for orbital wavefunctions and negative ...

The hypercentral Constituent Quark Model and its application to baryon properties

, 2015
The hypercentral Constituent Quark Model (hCQM) for the baryon structure is reviewed and its applications are systematically discussed. The model is based on a simple form of the quark potential, which contains a Coulomb-like interaction and a ...

The quark model

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 ...

Ideal quarks and mesons in the relativistic quark model

Physical Review C, 1994
We 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.

A quark statistical model for quark fragmentation

Lettere al Nuovo Cimento, 1982
A simple model for fragmentation of a quark into a jet of hadrons is presented. It is based on a quark statistical consideration and treats both mesons and baryons on equal footing.

Massive quarks and the quark-parton model

Physical Review D, 1974
The parton-model result $\ensuremath{\nu}{W}_{2}(x)=\ensuremath{\Sigma}{i}^{}{{e}_{i}}^{2}x{f}_{i}(x)$ is derived for massive quarks in the case where partons are identified as quarks. A simple model of a bound-quark system is also given in order to illuminate the ideas behind the derivation.
