DARWIN's sensitivity to the neutrinoless double beta decay published in EPJ-C

The DARWIN Collaboration has recently published the projected sensitivity of the DARWIN observatory to the neutrinoless double beta decay of 136Xe.

The analysis, based on a detailed Monte Carlo simulation of the background, shows that the experiment can achieve a half-life sensitivity of 2.4 x 1027 years for an exposure of 5 t (natural xenon) and 10 years.  Our group has significantly contributed to this study, which confirms that DARWIN, the ultimate  dark matter experiment, will be in addition comparable in its science reach to dedicated double beta decay experiments. The details of the analysis can be found in Eur. Phys. J. C 80. 808 (2020).
