$\Lambda N$ correlations from the stopped $K^{-}$ reaction on ${}^4$He

Abstract

We have investigated correlations of coincident $\Lambda N$ pairs from the stopped $K^{-}$ reaction on ${}^4$He, and clearly observed $\Lambda p$ and $\Lambda n$ branches of the two-nucleon absorption process in the $\Lambda N$ invariant mass spectra. In addition, non-mesonic reaction channels, which indicate possible exotic signals for the formation of strange multibaryon states, have been identified.
