Description
Intense $K^-$ beam at J-PARC will enable us to investigate strangeness $-2$ systems, namely $\Xi$-hypernuclei and double-$\Lambda$ hypernuclei. In particular, the high-resolution S-2S spectromter will be a key ingredient for a systematic study of these systems by means of $(K^-,K^+)$ reactions.
The J-PARC E75 experiment plans to produce $^5_{\Lambda\Lambda}{\mathrm{H}}$ as a decay product of $^{7}_{\Xi}{\mathrm{H}}$. In the first phase, we will investigate the formation of $^{7}_{\Xi}{\mathrm{H}}$ by the $^7\mathrm{Li}(K^-,K^+)$ reaction.
We will report the outline of the E75 experiment.
