| Outline of Final Research Achievements |
Fully automated systems were successfully built for following Xi- particles and for whole-area scanning to detect double-hypernuclei in nuclear emulsion with speed in several hundreds’ faster than the past one. The later system gave us an evidence for the presence of Xi-hypernucleus (named KISO Event), for the first time in the world, in the emulsion of the previous experiment, and then we found that an attractive nuclear-force would play between Xi- particle and nucleus.
In preparation of the E07 experiment at J-PARC, we made emulsion plates of 2.1 ton Gel and stocked them in the KAMIOKA mine, and it was achieved for driving solid-state tracking detector, X-ray detector (Hyperball-X) and detectors along the beam line. Therefore our experiment is recommended to run beam exposure in 2016 with the top priority. In theoretical research, it was pointed out that repulsive-force effect of p-wave on the Lambda-Lambda interaction had a great influence on the maximum mass of the neutron star.
