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…

Resonance-like structure near the $η d$ threshold in the $γ d$ { $\to$ } $π^{0} η d$ reaction

T. Ishikawa, H. Fujimura, H. Fukasawa +34

To investigate the interaction between the nucleon $N$ and nucleon resonance $N (1535) 1/ 2^{-}$ , the $η d$ threshold structure connected to the isoscalar $S$ -wave $N$ - $N (1535) 1/ 2^{-}$ sys…

Observation of a $K ˉ N N$ bound state in the $^{3} He (K^{-}, Λ p) n$ reaction

T. Yamaga, S. Ajimura, H. Asano +66

We have performed an exclusive measurement of the $K^{-} +^{3} He \to Λ p n$ reaction at an incident kaon momentum of $1 GeV / c$ .In the $Λ p$ invariant mass spectrum, a…

$ω N$ scattering length from $ω$ photoproduction on the proton near the threshold

T. Ishikawa, H. Fujimura, H. Fukasawa +35

Photoproduction of the $ω$ meson on the proton has been experimentally studied near the threshold. The total cross sections are determined at incident energies ranging from 1.09 to…

" $K^{-} p p$ ", a $K$ -Meson Nuclear Bound State, Observed in $^{3} He (K^{-}, Λ p) n$ Reactions

PARC E15 collaboration, S. Ajimura, H. Asano +67

We observed a distinct peak in the $Λ p$ invariant mass spectrum of $^{3} He (K^{-}, Λ p) n$ , well below the mass threshold of $m_{K} + 2 m_{p}$ . By selecting a relatively large mome…

An event mixing technique for Bose-Einstein correlations of two pions in photoproduction around 1 GeV

Qing-Hua He, H. Fujimura, H. Fukasawa +32

We have developed an event mixing technique to observe Bose-Einstein correlations (BEC) between two identical neutral pions produced in photo-induced reactions in the non-perturbat…
