This contribution describes a recent experimental study of the A(Kstop−,π±Σ∓)A′ reaction on light nuclei, Li6,7, Be9, C13 and O16. Final π±Σ∓π±Σ∓ pairs arise from π+π−nπ+π−n events. For some nuclei, the π+π+ momentum spectrum presents peak-strucures in the kinematical interval of formation of Σ-hypernuclear states. The apparatus used for the investigation is the FINUDA spectrometer set at DAΦNE.

Abstract
This contribution describes a recent experimental study of the A(Kstop−,π±Σ∓)A′ reaction on light nuclei, Li6,7, Be9, C13 and O16. Final π±Σ∓π±Σ∓ pairs arise from π+π−nπ+π−n events. For some nuclei, the π+π+ momentum spectrum presents peak-strucures in the kinematical interval of formation of Σ-hypernuclear states. The apparatus used for the investigation is the FINUDA spectrometer set at DAΦNE.
