Development of a Neural Network-Based Background Suppression Technique for $\Sigma N$ Cusp Spectroscopy at J-PARC

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

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