Le résumé fourni par la source

Abstract The broad physics reach of the LUX-ZEPLIN (LZ) experiment covers rare phenomena beyond the direct detection of dark matter. We report precise measurements of the extremely rare decay of 124 Xe through the process of two-neutrino double electron capture, utilizing a 1.39 kg × yr isotopic exposure from the first LZ science run. A half-life of T 1 / 2 2 ν 2 EC = ( 1.09 ± 0.1 4 stat ± 0.0 5 sys ) × 1 0 22 yr is observed with a statistical significance of 8.3 σ , in agreement with literature. First empirical measurements of the KK capture fraction relative to other K-shell modes were conducted, and demonstrate consistency with respect to recent signal models at the 1.4 σ level.
