Investigation of the $\bar{K}$--$^{6}$Li Interaction and the Search for the $Λ(1405)$ Resonance

We investigate the interaction of an antikaon ($K^-$) with the $^{6}$Li nucleus, described as an $α+ d$ cluster system. The study aims to explore the formation of the $Λ(1405)$ resonance through the $K^-d$ subsystem in the presence of a spectator $α$ particle. In the absence of dedicated experimental data for this reaction, particular attention is given to providing quantitative predictions for the manifestation of the $Λ(1405)$ structure in low-energy $\bar{K}N$ dynamics within a light nuclear environment. Employing different models of the $\bar{K}N-πΣ$ interaction, we calculate the $πΣn$ invariant-mass spectra and the $α$-particle missing-mass spectra, thereby identifying robust features of the $Λ(1405)$ signal and offering guidance for future experimental investigations.

Investigation of the $K^{-}pp$ Bound State via the \( K^{-} + {}^{3}\mathrm{He} \) Reaction

Using the four-body Alt-Grassberger-Sandhas (AGS) equations for the \( K^{-}ppn \) system, we investigate the possible formation of a \( K^{-}pp \) quasi-bound state through the low-energy \( K^{-} + {}^{3}\mathrm{He} \) reaction. The neutron missing mass spectrum in the final state was calculated for different models of the \( \bar{K}N \) interaction. The results indicate that, irrespective of the specific nature of the \( Λ(1405) \) structure or the details of the \( \bar{K}N \) interaction model, a signal corresponding to the \( K^{-}pp \) quasi-bound state could appear in the \( πΣp \) mass spectrum. This supports the feasibility of observing the \( K^{-}pp \) cluster in low-energy kaon-induced reactions on helium-3.
