Double-Weak Decays of ${}^{124}$Xe and ${}^{136}$Xe in the XENON1T and XENONnT Experiments

E. Aprile, K. Abe, F. Agostini +157

We present results on the search for double-electron capture ($2\nu \text{ECEC}$) of ${}^{124}$Xe and neutrinoless double-$\beta$ decay ($0\nu \beta \beta$) of ${}^{136}$Xe in XENON1T. We consider captur…
