Measurement of the Xe136 two-neutrino double- β -decay half-life via direct background subtraction in NEXT
Year: 2022
Type: article
Abstract: We report a measurement of the half-life of the $^{136}\mathrm{Xe}$ two-neutrino double-$\ensuremath{\beta}$ decay performed with a novel direct-background-subtraction technique. The analysis relies on the data collected with the NEXT-White detector operated with $^{136}\mathrm{Xe}$-enriched and $^{136}\mathrm{Xe}$-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 $2.{34}_{\ensuremath{-}0.46}^{+0.80}{\text{(stat)}}_{\ensuremath{-}0.17}^{+0.30}\text{(sys)}\ifmmode\times\else\texttimes\fi{}{10}^{21}\phantom{\rule{3.33333pt}{0ex}}\text{yr}$ is derived from the background-subtracted energy spectrum. The presented technique demonstrates the feasibility of unique background-model-independent neutrinoless double-$\ensuremath{\beta}$-decay searches.
