We presented the results of a study of the ULTIMATE team and colleagues at an APPEC community meeting in London.
Neutrinoless double beta decay with DARWIN

Model of the 40t LXe detector DARWIN.

Together with our friends and colleagues of the ERC project Xenoscope at the University of Zurich, the Freiburg team of the ERC project ULTIMATE has developed a Monte Carlo model of an ultimate 40t liquid xenon (LXe) detector and used it to predict its background. This allowed us to study the sensitivity of this detector, maybe realized in the framework of the DARWIN collaboration, to the neutrinoless double beta decay of 136Xe. The interesting catch is that we want to build the detector mainly to search for dark matter. The sensitivity to neutrinoless double beta decay comes for free and is very competitive, even without expensive isotopic enrichment.

Prof. Schumann from the ULTIMATE team presented the results of the study at the APPEC Community Meeting on neutrinoless double beta decay in London on October 31, 2019. Link to the presentation.
