Production of hyperon resonances induced by kaon on a deuteron target

Abstract

The $K^{-}d\to \pi YN$reaction is theoretically studied so as to investigate the $K^{-}$-induced production of the hyperon resonances $\Sigma (1385)$ and $\Lambda (1405)$. For this purpose we take into account the p-wave amplitudes for the meson-baryon two-body scatterings as well as the s-wave amplitudes. Due to the fact that the hyperon resonances are selectively produced from the $\bar{K}N$ channel in this reaction, the $\Lambda (1405)$ peak appears at 1420 MeV, which implies that $\Lambda (1405)$ and $\Sigma (1385)$ could be separately seen in the missing mass spectrum of the emitted nucleon in the $K^{-}d\to nX$ reaction. The $\pi Y$ invariant mass spectrum in this study is consistent with experimental data both for $\Sigma (1385)$ and $\Lambda (1405)$. The pion exchange contributions are also included and are found to give smooth background without distorting the peak structure of the hyperon resonances.
