The isotope $^{124}$Xe is exceedingly rare and long-lived. Still, its two-neutrino and neutrinoless double-weak decays offer exciting opportunities for neutrino and nuclear physics. Its double-beta decays with neutrinos would provide constraints for nuclear
matrix element calculations in the proton-rich region of the nuclear chart [C. Wittweg, B. Lenardo, A. Fieguth and C. Weinheimer, EPJ C...
Detection of neutrinoless double-beta decay ($0\nu\beta\beta$) would be an evidence of Majorana nature of neutrino, which clue on the extremely light neutrino mass and the matter dominant universe.
The KamLAND-Zen experiment started a search for $0\nu\beta\beta$ of $^{136}$Xe nuclei in 2011 (KamLAND-Zen400). The experiment was upgraded in 2019 by double amount of xenon nuclei and a tenfold...
The dual-phase xenon time-projection chamber (TPC) has risen in recent decades as one of the best technologies to hunt for dark matter in the form of weakly interacting massive particles (WIMPs). This xenon TPC has many advantages, including self-shielding against backgrounds, low threshold, good energy resolution, potential scalability for future larger detectors which could probe the WIMP...
