title = "Measurement of the Xe 136 two-neutrino double- β -decay half-life via direct background subtraction in NEXT",
abstract = "We report a measurement of the half-life of the Xe136 two-neutrino double-β 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-β-decay searches.",
