Development of a Neural Network-Based Background Suppression Technique for $I^£ N$ Cusp Spectroscopy at J-PARC

K. Amemiya, Y. Ichikawa, S. H. Hayakawa +8

A clear spectral enhancement, known as the `` $I^£ N$ cusp'', has been observed near the $I^£ N$ threshold in the $d (K^{-}, I ¨ ^{-})$ reaction. To understand the dynamical origin of this enh…

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 $(K^{-}, K^{+} I^^{-})$ and $^{12}$ C $(K^{-}, K^{+} I^ I^)$ Reactions at 1.8 GeV $/ c$

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

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