First Measurement of the $K^{-}$ Escape Cross Section in the $^{12} C (K^{-}, p)$ Reaction

Fumiya Oura, Yudai Ichikawa, Junko Yamagata-Sekihara +32

We investigated the $K ˉ$ -nucleus interaction through the simultaneous measurement of the inclusive $^{12} C (K^{-}, p)$ and exclusive $K^{-}$ -escape $^{12}{\rm C}(K^-, p K^-_{…

Cross section Measurements for $^{12}$ C $(K^{-}, K^{+} Ξ^{-})$ and $^{12}$ C $(K^{-}, K^{+} ΛΛ)$ Reactions at 1.8 GeV $/ c$

Woo Seung Jung, Yudai Ichikawa, Byung Min Kang +30

We present a measurement of the production of $Ξ^{-}$ and $ΛΛ$ in the $^{12}$ C $(K^{-}, K^{+})$ reaction at an incident beam momentum of 1.8 GeV/ $c$ , based on high-statistics dat…

Observation of Coulomb-assisted nuclear bound state of $Ξ^{-}$ - $^{14}$ N system

S. H. Hayakawa, K. Agari, J. K. Ahn +95

In an emulsion-counter hybrid experiment performed at J-PARC, a $Ξ^{-}$ absorption event was observed which decayed into twin single- $Λ$ hypernuclei. Kinematic calculations enabled a…

Observation of Spin-Dependent Charge Symmetry Breaking in $Λ N$ Interaction: Gamma-Ray Spectroscopy of $_{Λ}^{4}$ He

T. O. Yamamoto, M. Agnello, Y. Akazawa +51

The energy spacing between the ground-state spin doublet of $_{Λ}^{4}$ He(1 $^{+}$ ,0 $^{+}$ ) was determined to be $1406 \pm 2 \pm 2$ keV, by measuring $γ$ rays for the $1^{+} \to 0^{+}$ transitio…
