| dc.description | We suggest an effective quark model for low-lying baryon octet and decuplet motivated by QCD with a linearly rising confinement potential incorporating the extended Nambu-Jona-Lasinio (ENJL) model with linear realization of chiral U(3)XU(3) symmetry. Baryons are considered as external heavy states coupled to local three-quark currents with fixed spinorial structure and to low-lying mesons through quark-meson interactions defined in the ENJL--model. In the constituent quark loop representation we have calculated the coupling constants of the (pi NN), (pi N Delta) and (gamma N Delta) interactions and the (sigma_{πN})-term. The obtained results are in reasonable agreement with experimental data and other effective field theory approaches. | |
