Dark Matter and Cosmic Phenomena

The LUX-ZEPLIN (LZ) experiment will enable a neutrinoless double $\ensuremath{\beta}$ decay search in parallel to the main science goal of discovering dark matter particle interactions. We report the expected LZ sensitivity to $^{136}\mathrm{Xe}$ neutrinoless double $\ensuremath{\beta}$ decay, taking advantage of the significant ($>600$ kg) $^{136}\mathrm{Xe}$ mass contained within the active volume of LZ without isotopic enrichment. After 1000 live-days, the median exclusion sensitivity to the half-life of $^{136}\mathrm{Xe}$ is projected to be $1.06\ifmmode\times\else\texttimes\fi{}{10}^{26}$ years (90% confidence level), similar to existing constraints. We also report the expected sensitivity of a possible subsequent dedicated exposure using 90% enrichment with $^{136}\mathrm{Xe}$ at $1.06\ifmmode\times\else\texttimes\fi{}{10}^{27}$ years.
