The analysis relies on the data collected with the NEXT-White detector operated with Xe-136-enriched and Xe-136-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) x 10(21) yr is derived from the background-subtracted energy spectrum. The presented technique demonstrates the feasibility of unique background-model-independent neutrinoless double-beta-decay searches.", optnote="WOS:000810927800003", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5263), last updated on Tue, 28 Jun 2022 10:07:38 +0000", issn="2469-9985", doi="10.1103/PhysRevC.105.055501", opturl="https://arxiv.org/abs/2111.11091", opturl="https://doi.org/10.1103/PhysRevC.105.055501", language="English" }
