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…

Second gadolinium loading to Super-Kamiokande

K. Abe, C. Bronner, Y. Hayato +246

The first loading of gadolinium (Gd) into Super-Kamiokande in 2020 was successful, and the neutron capture efficiency on Gd reached 50\%. To further increase the Gd neutron capture…

Precise lifetime measurement of $_{Λ}^{4}$ H hypernucleus using in-flight $^{4}$ He $(K^{-}, π^{0})_{Λ}^{4}$ H reaction

T. Akaishi, H. Asano, X. Chen +35

We present a new measurement of the $_{Λ}^{4}$ H hypernuclear lifetime using in-flight $K^{-}$ + $^{4}$ He $\to$ $_{Λ}^{4}$ H + $π^{0}$ reaction at the J-PARC hadron facility. We demonstrat…

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…

Measurement of differential cross sections for $Σ^{+} p$ elastic scattering in the momentum range 0.44-0.80 GeV/c

PARC E40 Collaboration, T. Nanamura, K. Miwa +69

We performed a novel $Σ^{+} p$ scattering experiment at the J-PARC Hadron Experimental Facility. Approximately 2400 $Σ^{+} p$ elastic scattering events were identified from $4.9 \times…
