| 英文摘要 | A chiral quark-model approach is extended to the study of the (K) over barN scattering at low energies. The process of K(-)p -> Sigma(0)pi(0) at P-K less than or similar to 800 MeV/c (i.e the center mass energy W less than or similar to 1.7 GeV) is investigated The Lambda(1405)S-01 dominates the reactions over the energy region considered here Around P-K similar or equal to 400 MeV/c, the Lambda(1520)D-03 is responsible for a strong resonant peak in the cross section. Our analysis suggests that there exist configurations mixings within the Lambda(1405)S-01 and Lambda(1670)S-01 as admixtures of the [70, (2)1, 1/2] and [70, (2)8, 1/2] configurations. The Lambda(1405)S-01 is dominated by [70, (2)1, 1/2], and Lambda(1670)S-01 by [70, (2)8, 1/2] The non-resonant background contributions, i.e. u-channel and t-channel, also play important, roles in the explanation of the angular distributions due to amplitude interferences. |
