Observation of Coulomb-assisted nuclear bound state of $Ξ^{-}$ - $^{14}$ N system

S. H. Hayakawa, K. Agari, J. K. Ahn +95

In an emulsion-counter hybrid experiment performed at J-PARC, a $Ξ^{-}$ absorption event was observed which decayed into twin single- $Λ$ hypernuclei. Kinematic calculations enabled a…
