Neutrinoless double beta decay ($0 \nu \beta \beta$) provides a way to probe physics beyond the Standard Model of particle physics. The upcoming nEXO experiment will search for $0\nu\beta\beta$ in $^{136}$Xe with projected half-life sensitivity exceeding $10^{28}$ years at 90\% confidence level using liquid xenon (LXe) Time Projection Chamber (TPC) filled 5 tonnes Xe enriched $\sim$90\% $\beta \beta$-decaying isotope $^{136}$Xe. In parallel, potential future upgrade is being investigated aim...
Neutrinoless double beta decay (0νββ) provides a way to probe physics beyond the Standard Model of particle physics. The upcoming nEXO experiment will search for 0νββ in 136Xe with projected half-life sensitivity exceeding 1028 years at 90% confidence level using liquid xenon (LXe) Time Projection Chamber (TPC) filled 5 tonnes Xe enriched ∼90% ββ-decaying isotope 136Xe. In parallel, potential future upgrade is being investigated aim further suppress radioactive backgrounds and confirm...
Abstract We study a possible calibration technique for the nEXO experiment using 127 Xe electron capture source. is next-generation search neutrinoless double beta decay (0 νββ ) that will use 5-tonne, monolithic liquid xenon time projection chamber (TPC). The xenon, used both as source and detection medium, be enriched to 90% in 136 Xe. To optimize event reconstruction energy resolution, calibrations are needed map position- time-dependent detector response. 36.3 day half-life of its small...
