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…

Structure near $K^{-}$ + $p$ + $p$ threshold in the in-flight $^{3}$ He $(K^{-}, Λ p) n$ reaction

PARC E15 Collaboration, Y. Sada, S. Ajimura +69

To search for an S= -1 di-baryonic state which decays to $Λ p$ , the $^{3} He (K^{-}, Λ p) n_{mi ss in g}$ reaction was studied at 1.0 GeV/ $c$ . Unobserved neutrons were kinematically ide…

$Σ^{-} p$ emission rates in $K^{-}$ absorptions at rest on $^{6}$ Li, $^{7}$ Li, $^{9}$ Be, $^{13}$ C and $^{16}$ O

FINUDA Collaboration, M. Agnello, L. Benussi +32

An experimental study of the $K_{s t o p}^{-} A \to Σ^{-} p A^{'}$ reaction on $A =^{6}$ Li, $^{7}$ Li, $^{9}$ Be, $^{13}$ C and $^{16}$ O $p$ -shell nuclei is presented. The data were collected by…
