TL;DR: In this paper, the authors performed a coincidence measurement of two nucleons emitted from the nonmesonic weak decay (NMWD) of 5ΛHe and 12ΛC formed via the ( π +, K + ) reaction.

TL;DR: In this article, a new channel of NMWD, namely the recently confirmed three-body channel, seems to have a surprisingly big branching ratio so that it makes its accurate measurement prerequisite of the baryon-baryon weak interaction study.

TL;DR: In this article, the discrepancy of asymmetry parameter between experimental and theoretical values has been solved and the I = 1/2 rule for ΔS = 1 decay would hold or not in NMWD.

TL;DR: In this article, it was shown that the universal quenching of nucleon yields from the prediction of one-nucleon induced (1N-) NMWD can be explained by a fairly large contribution of the three-body process (Γ2N) in Γnm.
