15 summary J-PARC E07 is the most complex emulsion experiment so far to investigate double hypernuclei with Hybrid emulsion method. Beam exposure and photographic processing has been completed successfully. Event hunting is ongoing. Current statistics of E07 is more than twice that of E events of 3-vertex topology are found, so far. Several events are identified. These events will be published in the near future. We will continue the event hunting. Main search work will finished in about 1 year. 15
