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…

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…

" $K^{-} p p$ ", 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…

Missing-mass spectroscopy with the $^{6}$ Li( $π^{-}, K^{+}$ )X reaction to search for $_{Λ}^{6}$ H

R. Honda, M. Agnello, J. K. Ahn +63

We searched for the bound state of the neutron-rich $Λ$ -hypernucleus $_{Λ}^{6}$ H, using the $^{6}$ Li( $π^{-}, K^{+}$ )X double charge-exchange reaction at a $π^{-}$ beam momentum o…

Interference effect between $ϕ$ and $Λ (1520)$ production channels in the $γ p \to K^{+} K^{-} p$ reaction near threshold

S. Y. Ryu, J. K. Ahn, T. Nakano +69

The $ϕ$ - $Λ (1520)$ interference effect in the $γ p \to K^{+} K^{-} p$ reaction has been measured for the first time in the energy range from 1.673 to 2.173 GeV. The relative phases between…
