摘要：

The most stringent limit on the neutrinoless double beta decay halflife of Xe-136 is set by KamLAND-Zen at T-1/2 > 2.3 . 3 x 10(26 )yr. The experiment's sensitivity is limited by long-lived radioactive isotopes produced from muon spallation of xenon nuclei in the xenon-doped liquid scintillator. The long lifetimes of the isotopes, typically up to several days, challenge the creation of an efficient tagging method, currently achieving only 42 +/- 8.8%. . 8%. We summarise the tagging techniques for both light and heavy spallation isotopes employed in KamLAND-Zen, and highlight the critical role of FLUKA simulations in developing new veto strategies.
