摘要：
<正> The low-energy region kaon-pion S-and P-wave phase shifts with isospin I = 1/2 and I = 3/2 aredynamically studied in the chiral SU(3) quark model by solving a resonating group method equation. The modelparameters are taken to be the values fitted by the energies of the baryon ground states and the kaon-nucleon elasticscattering phase shifts of different partial waves. As a preliminary study the s-channel qq annihilation interactions are notincluded since they only act in the very short range and are subsequently assumed to be unimportant in the low-energydomain. The numerical results are in qualitative agreement with the experimental data.
