The quark-diquark approximations of the three-quark structure of a nucleon are considered in the framework of the quark confinement model (QCM) based on definite concepts of the hadronization and quark confinement. The static nucleon characteristics (magn...

A qualitative discussion is given of the theoretical and experimental implications of the quark model. Courses for future research are considered.
Octet (1(sup +)/2) and decuplet (3(sup +)/2) of baryons as relativistic three-quark states are investigated in the quark confinement model (QCM), the relativistic quark model, based on some assumptions about hadronization and quark confinement. The ...
On the level of an effective quark theory, we define confinement by the absence of quark anti-quark thresholds in correlation function. We then propose a confining Nambu-Jona-Lasinio-type model. The confinement is implemented in analogy to Anderson locali...
The quark cluster model is used to investigate the structure of the three-nucleon systems. The nucleon-nucleon interaction is proposed considering the colour-nucleon clusters and incorporating the quark degrees of freedom. The quark-quark potential in the...
Theoretical approaches to deal with the problem of quarks in nuclei, ranging from direct application of QCD to phenomenological quark models are reviewed. The description of the nucleon-nucleon interaction on the basis of the quark-quark interaction, and ...
Quark models of the two-nucleon interaction are reviewed with particular emphasis on calculations in the MIT bag model.

Composite models of quarks, leptons and Higgs bosons are described and discussed. The fermion models considered are those in which the basic concepts are abstracted from the quark model of nucleon structure; the quark model paradigm thus serves as a ...
The Single Transverse - Spin Asymmetry (SSA) is analysed in the framework of the Strongly Correlated Quark Model proposed by author, where the proton spin emerges from the orbital momenta of quark and qluon condensates circulating around the valence quarks. It is shown that dominating factors of appearance of SSA ...

A simple model of confined quarks is presented which resembles the massive quark model in the calculation of structure functions and which has the property that it is manifestly consistent with current algebra.

1) First, various subquark models so far proposed are briefly reviewed. Classifications of leptons and quarks in the models and their comparison are made. Our spinor-subquark model of leptons and quarks in which leptons and quarks are made of three subqua...
Quark-lepton symmetric models are a new class of gauge theories which unify the quarks and leptons. In these models the gauge group of the standard model is extended to include a color group for the leptons, and consequently the quarks and leptons can the...
An extension and generalization of the quark rearrangement model of baryon annihilation is described which can be applied to all annihilation reactions and which incorporates some of the features of the highly successful quark parton model. Some p anti-p interactions are discussed. (JFP)
The electromagnetic properties of baryons are investigated in the framework of a relativistic quark model. The model includes beyond the usual single quark transition ansatz relativistic effects due to the strong interaction and confinement forces between...
