2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/204904We have investigated correlations of coincident $ΛN$ pairs from the stopped $K^-$ reaction on ${}^4$He, and clearly observed $Λp$ and $Λn$ branches of the two-nucleon absorption process in the $ΛN$ invariant mass spectra. In addition, non-mesonic reaction channels, which indicate possible exotic signals for the formation of strange multibaryon states, have been identified.5 pages, 3 figures, submitted to Physical Review LettersNuclear Experimenttext
