Since the shutdown of several old proton synchrotrons, which played a fundamental role in
the second generation experiments in hypernuclear physics performed in Europe, USA and …

In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ-absorption event was
observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a …

The differential cross sections of the Σ-p→ Λ n reaction were measured accurately for the Σ-
momentum (p Σ) ranging from 470 to 650 MeV/c at the J-PARC Hadron Experimental …

The aim of the hadron physics research programs conducted at J-PARC is to explore the
structure of hadronic matter using the world's highest-intensity meson beams. Since the first …

A high statistics Σ p scattering experiment is performed at the J-PARC Hadron Experimental
Facility. Momentum-tagged Σ− s running in a liquid hydrogen target are accumulated by …

A double-hypernucleus,, was observed by the J-PARC E07 Collaboration in nuclear
emulsions tagged by the () reaction. This event was interpreted as the production and decay …

We have observed a “”-like structure in the reaction at 1.69 GeV. In this reaction, a hyperon
resonance is expected to be produced as a doorway to form through the process. However …

We performed a novel Σ+ p scattering experiment at the J-PARC Hadron Experimental
Facility. Approximately 2400 Σ+ p elastic scattering events were identified from 4.9× 107 …

We have carried out an experiment to search for a neutron-rich hypernucleus, H Λ 6, by the
Li 6 (π−, K+) reaction at p π−= 1.2 GeV/c. The obtained missing-mass spectrum with an …

Three beam lines for secondary charged particles are constructed in the hadron
experimental hall of J-PARC. The K1. 8 beam line, which incorporates two separators …
