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…

Measurement of the strong interaction induced shift and width of the 1s state of kaonic deuterium at J-PARC

J. Zmeskal, M. Sato, S. Ajimura +74

The antikaon-nucleon interaction close to threshold provides crucial information on the interplay between spontaneous and explicit chiral symmetry breaking in low-energy QCD. In th…

Three- and four-nucleon absorption processes observed in the $K^{-}$ - $^{4}$ He reaction at rest

T. Suzuki, H. Bhang, J. Chiba +23

Correlations of back-to-back coincident $Λ d$ and $Λ t$ pairs from the stopped $K^{-}$ reaction on $^{4}$ He had been investigated, thereby $Λ d$ and $Λ t$ branches of non-mesonic three- an…

$Λ d$ correlations from the $^{4}$ He(stopped- $K^{-}$ , $d$ ) reaction

T. Suzuki, H. Bhang, J. Chiba +23

We have observed an intense high-energy component in an inclusive $^{4}$ He(stopped $K^{-}$ , $d$ ) spectrum. For back-to-back $Λ d$ pairs a prominent event cluster has been found just bel…
