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…
