The chiral SU(3) quark model is extended to include coupling between vector chiral field and quarks. By using this model, the phase shifts of NN scattering for different partial waves are studied. The results are very similar to those of the chiral SU(3) quark model calculation, in which one gluon exchange (OGE) plays dominate role in the short range part of the quark-quark interactions. Only i...

Since the observation of the top quark in 1995, considerable progress has been made by the CDF and D0 collaborations in measuring top quark production and decay properties. The combined top quark mass from both experiments is mt = 174:3 5:1 GeV/c . With this determination of the top quark mass, the remaining properties of the top quark are predicted by the standard model, allowing for many new ...

Weak current-induced baryonic form factors at zero recoil are evaluated in the rest frame of the heavy parent baryon using the nonrelativistic quark model. Contrary to previous similar work in the literature, our quark model results do satisfy the constraints imposed by heavy quark symmetry for heavy-heavy baryon transitions. Assuming a dipole q behavior, we have applied the quark model form fa...

This article is devoted to the processes with participation of t-quark. The top quarks are one most amazing elementary particles. Predictions characteristics various interactions involving -quark have high theoretical accuracy, as well has large production cross section which makes it a unique laboratory for testing Standard Model and beyond. quark important objects in searches new effects. rev...

Using a relativistic constituent quark model based on point form of relativistic quantum mechanics with given set of degrees of freedom we investigate electroweak decays of the pion and ρ mesons. All free parameters of quark model (the mass u(d) -quark and parameters which determines the confinement scale) are fixed by using relevant experimental data. Leptonic Decays of Mesons in a PoincareCov...
