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…

Search for Tetraneutron by Pion Double Charge Exchange Reaction at J-PARC

Hiroyuki Fujioka, Tomokazu Fukuda, Toru Harada +6

Tetraneutron ( $^{4} n$ ) has come back in the limelight, because of recent observation of a candidate resonant state at RIBF. We propose to investigate the pion double charge exchange…

Search for the deeply bound $K^{-} pp$ state from the semi-inclusive forward-neutron spectrum in the in-flight $K^{-}$ reaction on helium-3

Tadashi Hashimoto, Shuhei Ajimura, George Beer +64

An experiment to search for the $K^{-} pp$ bound state was performed via the in-flight $^{3}$ He( $K^{-}, n)$ reaction using 5.3 $\times$ $1 0^{9}$ kaons at 1 GeV/ $c$ at the J-PARC hadron exper…

Nucleon-nucleon coincidence measurement in the non-mesonic weak decay of 5_Lambda-He and 12_Lambda-C hypernuclei

S. Okada, S. Ajimura, K. Aoki +30

We have measured both yields of neutron-proton and neutron-neutron pairs emitted from the non-mesonic weak decay process of 5_Lambda-He and 12_Lambda-C hypernuclei produced via the…
