We examine mass-corrected SU(6) symmetry predictions in the quark model relating vector, axial-vector, and strong NN and NΔ couplings, and demonstrate that the experimental NΔ value is significantly h...
Electromagnetic properties of nucleons and hyperons in a Lorentz covariant quark model
Magnetic nuclear lorentz covariance the bound state quark let-down pseudo-scalar meson
2014/12/20
We calculate magnetic moments of nucleons and hyperons and N -> Delta + gamma transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound st...

$η$ photoproduction on the quasi-free nucleons in the chiral quark model
chiral quark model quasi-free nucleons
2011/7/20
A chiral quark-model approach is adopted to study the $\eta$ photoproduction off the quasi-free neutron and proton from a deuteron target. Good descriptions of the differential cross sections, total c...

A relativistic quark model with infrared confinement and the tetraquark state
Relativistic quark model confinement exotic mesons
2010/11/1
We explore the consequences of treating the X(3872) meson as a tetraquark bound state. As dynamical framework we employ a relativistic constituent quark model which includes infrared confinement in an...
Quark model study of multiquark states
quark model dibaryon tetraquark color confinement multibody interaction
2009/11/24
The six- and four-quark systems are studied in the framework of constituent quark models. It is emphasized that the color confinement used in multiquark system should be different from the one used in...
Λ resonances studied in K－p→Σ0π0 in a chiral quark model
strange resonance quark model meson-baryon interaction
2009/11/24
A chiral quark-model approach is extended to the study of the KN scattering at low energies. The process of K－p→Σ0π0 at PK\≤800 MeV/c (i.e. the center mass energy W≤1.7 GeV) is investigated. The Λ(140...
Study of nucleon resonances in a chiral quark model via η productions
N* chiral quark model photoproduction
2009/11/24
In this report we investigate η-meson productions on the proton via electromagnetic and hadron probes in a chiral quark model approach. The observables, such as, differential cross section and beam a...
