| 概要 | The $K^{-}$ induced production of $\Lambda(1405)$ in the $K^{-} d \to \pi<br />
\Sigma n$ reaction is investigated having in mind the conditions of the DAFNE<br /> facility at Frascati. We find that the fastest kaons from the decay of the<br /> $\phi$ at DAFNE are well suited to see this resonance if one selects forward<br /> going neutrons in the center of mass, which reduce the contribution of single<br /> scattering and stress the contribution of the double scattering where the<br /> signal of the resonance appears clearer. We take advantage to report briefly on<br /> a recent work in which in addition to the $\bar{K}NN$ system with total spin<br /> S=0, we find a less bound state (although with equally large width) with S=1,<br /> like in the $K^{-} d$ reported in the first part. |
