The LUX-ZEPLIN dark matter search aims to achieve a sensitivity to the WIMP-nucleon spin-independent cross-section down to (1–2)×10−12 pb at a WIMP mass of 40 GeV/c2. This paper describes the ...simulations framework that, along with radioactivity measurements, was used to support this projection, and also to provide mock data for validating reconstruction and analysis software. Of particular note are the event generators, which allow us to model the background radiation, and the detector response physics used in the production of raw signals, which can be converted into digitized waveforms similar to data from the operational detector. Inclusion of the detector response allows us to process simulated data using the same analysis routines as developed to process the experimental data.
Phys. Rev. C 102, 014602 (2020) The LUX-ZEPLIN (LZ) experiment will enable a neutrinoless double beta decay
search in parallel to the main science goal of discovering dark matter particle
...interactions. We report the expected LZ sensitivity to $^{136}$Xe neutrinoless
double beta decay, taking advantage of the significant ($>$600 kg) $^{136}$Xe
mass contained within the active volume of LZ without isotopic enrichment.
After 1000 live-days, the median exclusion sensitivity to the half-life of
$^{136}$Xe is projected to be 1.06$\times$10$^{26}$ years (90% confidence
level), similar to existing constraints. We also report the expected
sensitivity of a possible subsequent dedicated exposure using 90% enrichment
with $^{136}$Xe at 1.06$\times$10$^{27}$ years.
