J-PARC E07 is the most ambitious and complex emulsion experiment to date investigating double hypernuclei with Hybrid emulsion method. The physics run at the K1.8 beam line in the J-PARC hadron experimental facility have been completed in 2017. The emulsion sheets are presently being analyzed with dedicated optical microscopes. Current statistics are estimated to be more 3 times than that of previous experiments. Quantitative data on the
and
interaction are being accumulated successfully via analysis of double
and
hypernuclei. Multiple
hypernucleus candidates suggests several features about
hypernucleus that the identification efficiency of
C is significantly higher than other mode, many daughters of
C are identified as He or Be, and multiple bound states of
exist in the
N nucleus. An analysis of X-ray spectroscopy of
hyperatoms are ongoing.
