Search for Two-neutrino Double-Beta Decay of ${}^{136}\mathrm{Xe}$ to the $0_1^{+}$ excited state of ${}^{136}\mathrm{Ba}$ with the Complete EXO-200 Dataset

200 Collaboration, S. Al Kharusi, G. Anton +104

A new search for two-neutrino double-beta ($2\nu \beta \beta$) decay of ${}^{136}\mathrm{Xe}$ to the $0_1^{+}$ excited state of ${}^{136}\mathrm{Ba}$ is performed with the full EXO-200 dataset. A deep learnin…
