被引用回数:25 パーセンタイル:83.76(Physics, Multidisciplinary)A double- hypernucleus, , was observed by the J-PARC E07 collaborationin nuclear emulsions tagged by the reaction. This event was interpreted as a production and decay of ,, or via capture in .By assuming the capture in the atomic 3D state, the binding energy of two hyperons()of these double- hypernuclei are obtained to be, , and , respectively. Based on the kinematic fitting, is the most likely explanation for the observed event.
