Investigation of hypernuclei with strangeness -2, i.e. Ξ-hypernuclei and double-Λ hypernuclei, is one of the most important subjects in strangeness nuclear physics. For example, observation of new double-Λ hypernuclear events in nuclear emulsion are expected at the J-PARC E07 experiment, which is in the analysis stage. Reaction spectroscopy for the 12C(K-,K+)12ΞBe reaction is planned as the J-PARC E70 experiment.
We have conceived a novel counter experiment to investigate a double-Λ hypernucleus, 5ΛΛH, by means of decay pion spectroscopy. It can be produced by decay of 7Ξ-H, which can be tagged by reaction spectroscopy of the 7Li(K-,K+) reaction. We submitted a Letter of Intent to the J-PARC PAC in June 2018.
We will introduce the proposed experiment and report the current status of feasibility studies.
