| 摘 要： | The isospin I = 0 and I = 1 kaon-nucleon S and P partial waves phase shifts have been studied in the chiral SU(3) quark model by solving a resonating group method equation. When the parameters of the chiral fields are taken in a reasonable region, the numerical results of S-wave are in good agreement with the experimental data, and the P-wave phase shifts can also be explained qualitatively by the calculation of only central force considered.

| Abstract: | The isospin $I=0$ and $I=1$ kaon-nucleon S and P partial waves phase
shifts have been studied in the chiral SU(3) quark model by
solving a resonating group method equation. When the
parameters of the chiral fields are taken in a reasonable region,
the numerical results of S-wave are in good agreement with the
experimental data, and the P-wave phase shifts can also be
explained qualitatively by the calculation of only central force considered. |
