A chiral quark-model approach is extended to the study of the KN scattering at low energies. The process of K~-p→Σ~0π~0 at P_K≤ 800 MeV/c (i.e. the center m
We report our investigation on the octet baryon spectrum in the nonrelativistic quark model by taking into account the two-gluon exchange effect. The calculated
