Observation of the "K- pp"-like structure in the d( +, K+) reaction at 1.69 GeV/c
We have observed a “|$K^{-}pp$|”-like structure in the |$d(\pi ^{+ },K^{+ })$| reaction at 1.69 GeV|$/c$|. In this reaction, a |$\Lambda (1405)$| hyperon resonance is expected to be produced as a doorway to form |$K^{-}pp$| through the |$\Lambda ^{\ast }p\rightarrow K^{-}pp$| process. However, most of the |$\Lambda (1405)$| produced would …
