The LUX-ZEPLIN (LZ) experiment is projected to have high sensitivity in detecting the two-neutrino and neutrinoless double beta decay of Xe-134, with predicted exclusion values of half-lives up to 1.7 x 10(24) years and 7.3 x 10(24) years, respectively.
The projected sensitivity of the LUX-ZEPLIN (LZ) experiment to two-neutrino and neutrinoless double beta decay of Xe-134 is presented. LZ is a 10-tonne xenon time-projection chamber optimized for the detection of dark matter particles and is expected to start operating in 2021 at Sanford Underground Research Facility, USA. Its large mass of natural xenon provides an exceptional opportunity to search for the double beta decay of Xe-134, for which xenon detectors enriched in Xe-136 are less effective. For the two-neutrino decay mode, LZ is predicted to exclude values of the half-life up to 1.7 x 10(24) years at 90% confidence level (CL) and has a three-sigma observation potential of 8.7 x 10(23) years, approaching the predictions of nuclear models. For the neutrinoless decay mode LZ, is projected to exclude values of the half-life up to 7.3 x 10(24) years at 90% CL.
