Measurement of the mesonic decay branch of the $K ˉ N N$ quasi-bound state

T. Yamaga, S. Ajimura, H. Asano +67

We conducted measurements of $K^{-} +^{3} He \to π Y N + N^{'}$ reactions using a $1 GeV / c$ $K^{-}$ -beam, with the objective of understanding the broad decay width of $\bar…

Pole position of $Λ (1405)$ measured in $d (K^{-}, n) π Σ$ reactions

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

We measured a set of $π^{\pm} Σ^{\mp}$ , $π^{0} Σ^{0}$ , and $π^{-} Σ^{0}$ invariant mass spectra below and above the $K ˉ N$ mass threshold in $K^{-}$ -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 $q ˉ$ and quarks $q$ . The $q ˉ$ and $q$ pair has t…

Extension of the J-PARC Hadron Experimental Facility: Third White Paper

Kazuya Aoki, Hiroyuki Fujioka, Toshiyuki Gogami +40

The J-PARC Hadron Experimental Facility was constructed with an aim to explore the origin and evolution of matter in the universe through the experiments with intense particle beam…

Feasibility of an experimental search for a resonance of a pion and a light nucleus

Hiroyuki Fujioka

A hypothesis is proposed herein, suggesting that a pion-nuclear resonance may be observed in the $α + d \to^{6} Li (3.563) + π^{0}$ reaction. The resonance has a $π N N α$ structure,…

Energy dependent angular distribution of individual $γ$ -rays in the $^{139}$ La( $n$ , $γ$ ) $^{140}$ La* reaction

T. Okudaira, S. Endo, H. Fujioka +14

Neutron energy-dependent angular distributions were observed for individual $γ$ -rays from the 0.74 eV p-wave resonance of $^{139}$ La+ $n$ to several lower excited states of $^{140}$ …
