论文名称：Resonance model study on K + N→KNη near threshold

发表刊物：Phys.Rev. C

摘要：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.
