We have fitted the masses and elastic widths of the S=0 baryons in the context of the QCD-improved quark shell model. All states in the N =0, 1, 2 and 3 harmonic oscillator bands have been included. Three models for the decay of these states have been studied, and it is concluded...
(Atomic Physics)physicsany of a set of six hypothetical elementary particles together with their antiparticles thought to be fundamental units of all baryons and mesons but unable to exist in isolation. The magnitude of their charge is either two thirds or one third of that of the electron ...
Localized single-particle potentials for all octet baryons, $N$, $\Lambda$, $\Sigma$, and $\Xi$, in finite nuclei, $^{12}$C, $^{16}$O, $^{28}$Si, $^{40}$Ca, $^{56}$Fe, and $^{90}$Zr, are calculated using the quark-model baryon-baryon interactions. $G$-matrices eva...

The constituent quark model (CQM) has proven remarkably successful in accounting for a number of static properties of the lowest-lying baryons, most notably their magnetic moments. In the latter instance, one assumes each constituent quark possesses a distinct magnetic moment that is proportional to...
In the framework of the relativistic quasipotential quark model the mass spectrum of baryons with two heavy quarks is calculated. The quasipotentials for interactions of two quarks and of a quark with a scalar and axial vector diquark are evaluated. The bound state masses of baryons with J(...
A scalar-isoscalar quark-meson interaction is used to mix fundamental pseudoscalar mesons directly into the wave functions of baryons. The parameters of the model are constrained using properties of the ground-state baryon spectrum, such as charge radii, strong decay widths, and the pion-nucleon...
The magnetic moments of the baryon octet are calculated in time-ordered perturbation theory in the harmonic oscillator quark model, which is supplemented by a small Dirac quark wave function to include the pion-quark coupling at long distances. Relativistic, pionic and quark confinement corrections ...
