Development of a Neural Network-Based Background Suppression Technique for $\hat{I}\pounds N$ Cusp Spectroscopy at J-PARC

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

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