Observation of Coulomb-assisted nuclear bound state of -N system
S. H. Hayakawa, K. Agari, J. K. Ahn +95
In an emulsion-counter hybrid experiment performed at J-PARC, a absorption event was observed which decayed into twin single- hypernuclei. Kinematic calculations enabled a…

Development of an alpha-particle imaging detector based on a low radioactivity micro-time-projection chamber
H. Ito, T. Hashimoto, K. Miuchi +5
An important issue for rare-event-search experiments, such as the search for dark matter or neutrinoless double beta decay, is to reduce radioactivity of the detector materials and…

Observation of a Be double-Lambda hypernucleus in the J-PARC E07 experiment
H. Ekawa, K. Agari, J. K. Ahn +100
A double- hypernucleus, , was observed by the J-PARC E07 collaboration in nuclear emulsions tagged by the reaction. This event was interprete…
