Searching for Neutrinoless Double-Beta Decay of \(^{136}\)Xe with PandaX-4T

Searching for Neutrinoless Double-Beta Decay of \(^{136}\)Xe with PandaX-4T

We report the search for neutrinoless double-beta decay of \(^{136}\)Xe from the PandaX-4T experiment with a 3.7-tonne natural xenon target. The data reconstruction and the background modeling are optimized in the MeV energy region. A blind analysis is performed with data from the commissioning run...

Zusammenfassung:We report the search for neutrinoless double-beta decay of \(^{136}\)Xe from the PandaX-4T experiment with a 3.7-tonne natural xenon target. The data reconstruction and the background modeling are optimized in the MeV energy region. A blind analysis is performed with data from the commissioning run and the first science run. No significant excess of signal over the background is observed. A lower limit on the half-life of \(^{136}\)Xe neutrinoless double-beta decay is established to be \(2.1 \times 10^{24}\)~yr at the 90\% confidence level, with a \(^{136}\)Xe exposure of 44.6~kg\(\cdot\)year. Our result represents the most stringent constraint from a natural xenon detector to date.
