半个世纪以来，人们一直用核乳胶来寻找双Λ超核.我们已经有9个事例表明了原子核中两个单位的Λ超子的连续衰变，但是到目前为止，我们对Λ-Λ相互作用的认识仍然很贫乏。在以往乳胶实验的基础上，J-PARC的E07实验可望分别用混合乳胶法和整体扫描法再现~ 102和~ 103的事例。
Nuclear emulsion was used to search for double-Λhypernuclei for a half century. We have nine events showing sequential decay of two units ofΛhyperon in nucleus, however our knowledge ofΛ-Λinteraction is still poor, so far. Based on knowhow given by the past emulsion experiments, the E07 experiment at J-PARC is expected to present the events in ~102and ~103withHybrid-emulsionandOverall-scanningmethod, respectively.
