Direct experimental evidence of the weak $\Lambda n p \rightarrow n n p$ hypernucleus decay

Abstract

A direct experimental evidence of the occurrence of the weak reaction Λnpnnp\Lambda np\rightarrow nnp in nuclei has been obtained by the FINUDA experiment. Three events have been found that can be attributed to Λ7^{7}_{\Lambda}Li and Λ9^{9}_{\Lambda}Be two nucleon-induced non mesonic weak decays. The kinematic analysis of such events is presented here.
