Measurement of the Xe 136 two-neutrino double- ß -decay half-life via direct background subtraction in NEXT 2022 Access copy available to the general public Unrestricted We report a measurement of the half-life of the Xe136 two-neutrino double-ß decay performed with a novel direct-background-subtraction technique. The analysis relies on the data collected with the NEXT-White detector operated with Xe136-enriched and Xe136-depleted xenon, as well as on the topology of double-electron tracks. With a fiducial mass of only 3.5 kg of Xe, a half-life of 2.34-0.46+0.80(stat)-0.17+0.30(sys)×1021yr is derived from the background-subtracted energy spectrum. The presented technique demonstrates the feasibility of unique background-model-independent neutrinoless double-ß-decay searches. © 2022 American Physical Society. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.1 2022 PHYSICS, NUCLEAR 7 / 19 = 0.368 2022 Q2 T2 1.305 2022 Nuclear and High Energy Physics 2022 Q1 5.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sorel, M.
