Resonance model study on $K^{+}N\to KN\eta$ near threshold

Abstract

By using resonance model, we investigate $K^{+}N\to KN\eta$ reactions with the assumption that these reactions are dominated by the excitation of $N^{\ast }(1535)$ near threshold. It is found that the hyperon and $\rho$ exchange diagrams give the most important contributions to these reactions. Thus these reactions may be a good place to study the coupling of $N^{\ast }(1535)$ with $K\Lambda$, $K\Sigma$ and $N\rho$ channels. We demonstrate that the angular distributions of final particles provide useful information about the different mechanisms of the $N^{\ast }(1535)$ excitations, which could be useful for future experimental analysis on these reactions.
