First observation of a nuclear -state of hypernucleus,
M. Yoshimoto, J. K. Ahn, B. Bassalleck +46
Bound-systems of -- are studied via capture at rest followed by emission of a twin single- hypernucleus in the emulsion detectors. Two events forming…
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…
Observation of a bound state in the reaction
T. Yamaga, S. Ajimura, H. Asano +66
We have performed an exclusive measurement of the reaction at an incident kaon momentum of .In the invariant mass spectrum, a…
Mitigating the effects of charged particle strikes on TES arrays for exotic atom X-ray experiments
H. Tatsuno, D. A. Bennett, W. B. Doriese +16
Exotic atom experiments place transition-edge-sensor (TES) microcalorimeter arrays in a high-energy charged particle rich environment. When a high-energy charged particle passes th…
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…
"", a -Meson Nuclear Bound State, Observed in Reactions
PARC E15 collaboration, S. Ajimura, H. Asano +67
We observed a distinct peak in the invariant mass spectrum of , well below the mass threshold of . By selecting a relatively large mome…
