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…

Anti-deuteron beam study at J-PARC HEF K1.8 beam line

M. Ukai, Y. Ishikawa, T. Takahashi +2

We performed a $d$ beam study at the K1.8 beam line of J-PARC Hadron Experimental Facility. 1.8 GeV/ $c$ $d$ beam yield was measured to be 0.30 $\pm$ 0.04 coun…

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…
