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…

CNN-based event classification for alpha-decay events in nuclear emulsion
J. Yoshida, H. Ekawa, A. Kasagi +6
We developed an efficient classifier that sorts alpha-decay events from various vertex-like objects in nuclear emulsion using a convolutional neural network (CNN). Alpha-decay even…

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…
