Properties of nucleons in the relativistic quark model with strong binding

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Baryons are considered as the strongly bound system of three heavy quarks. The dynamics of the model is described by the Bethe-Salpeter equation with harmonic oscillator interaction. Two different spin structures of the interaction kernels (taken from the meson case) are considered. It is found that one of them fails to reproduce the spectrum of baryons in the ground state. The second spin structure reproduces the spectrum. The model gives good results for the magnetic moments of nucleons and for the weak currents matrix element between the neutron and proton. It is also shown that the properties of quark in our model are similiar to those of the quark model for mesons and thus both these models can be treated together.
