Baryons consist of three quarks, such as $$ \left| {p} \right\rangle = \left| {uud} \right\rangle $$ ,...
The quark-diquark approximation of the three-quark, structure of baryons is proposed. In the framework of this approach, the main low-energy characteristics of baryons, such as magnetic moments, electromagnetic radii and form factors, the ratio of axial and vector constants in semileptonic ...

The study of the baryon-baryon interaction based on the non-relativistic quark cluster model is reviewed. The structure of the wave functions for three-and six-quark systems and the description in terms of the resonating group method (RGM) are studied. The Hamiltonian for the multi-quark system...
Interactions between the octet-baryons (B8) in the spin–flavor SU6 quark model are investigated in a unified coupled-channels framework of the resonating-group method (RGM). The interaction Hamiltonian for quarks consists of the phenomenological confinement potential, the color Fermi–Breit interactio...
But to understand the structure of the new psi particle a fourth quark is very likely necessary, in the opinion of many researchers. Press Release: The 1976 Nobel Prize in Physics 1976 The result is what researchers call a quark-gluon plasma QGP, which hasn't been present in significant qu...
Radial excitations of low-lying baryons and the structure of the Z[sup +] penta–quark. Within the collective quantization scheme for chiral solitons we discuss states in higher dimensional representations of flavor SU(3) and their relation to... Weigel,Herbert - 《Aip Conference Proceedings》 ...

In addition to the quark-anti-quark assignment for a meson and three-quark interpretation of a baryon, it allows the existence of non-standard exotic states [1,2,3,4,5,6]. Since the observation of X(3872) in 2003 [1], many exotic candidates have been announced on the experimental ...
In the aspect of theory, the heavy-quark in a singly heavy baryon is decoupled from the two light-quarks in the heavy quark limit. With the requirement of the flavorSU(3) subgroups for the light-quarks, the baryons belong to either a sextet (6F) of the flavor symmetric states (ΣQ,...
