Has J-PARC E07 observed a Ξ1s− nuclear state?
The Strangeness S=−2 J-PARC E07 emulsion experiment published recently two new Ξ−–14N capture events, IRRAWADDY and IBUKI, identified by observing weak-decay sequences of pairs of single-Λ hypernuclei and interpreted as Ξ1s− and Ξ1p− nuclear bound states, respectively, with binding energies BΞ−1s=6....
