초록

A double- hypernucleus, , was observed by the J-PARC E07 Collaboration in nuclear emulsions tagged by the () reaction. This event was interpreted as the production and decay of , , or via capture in . By assuming capture in the atomic 3D state, the binding energies 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.
