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…

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…

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…

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…
