Precise lifetime measurement of H hypernucleus using in-flight HeH reaction

T. Akaishi, H. Asano, X. Chen +35

We present a new measurement of the H hypernuclear lifetime using in-flight + He H + reaction at the J-PARC hadron facility. We demonstrat…

Pole position of measured in reactions

PARC E31 Collaboration, S. Aikawa, S. Ajimura +74

We measured a set of , , and invariant mass spectra below and above the mass threshold in -induced reactions on deuteron. We deduced th…

Chiral symmetry restoration at high matter density observed in pionic atoms

Takahiro Nishi, Kenta Itahashi, DeukSoon Ahn +45

Modern theories of physics tell that the vacuum is not an empty space. Hidden in the vacuum is a structure of anti-quarks and quarks . The and pair has t…

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…
