| 论文简介 | By using resonance model, we investigate K + N→KNη reactions with the assumption that these reactions are dominated by the excitation of N ∗ (1535) near threshold. It is found that the hyperon and ρ exchange diagrams give the most important contributions to these reactions. Thus these reactions may be a good place to study the coupling of N ∗ (1535) with KΛ , KΣ and Nρ channels. We demonstrate that the angular distributions of final particles provide useful information about the different mechanisms of the N ∗ (1535) excitations, which could be useful for future experimental analysis on these reactions. |
