Search for the ${}^{16}\text{O}(ppp){\to }^{13}\text{C}{\pi }^{+}{\pi }^{+}{e}^{+}$ Decay Mode in Super-Kamiokande Using Machine Learning Techniques

Kamiokande Collaboration, J. Feng, K. Abe +296

We report a new partial lifetime limit of $4.2\times 10^{32}$ years for the trinucleon decay mode ${}^{16}\text{O}(ppp){\to }^{13}\text{C}{\pi }^{+}{\pi }^{+}{e}^{+}$, obtained from a searc…
