Sensitivity of the DARWIN observatory to the neutrinoless double beta decay of 136Xe — •Fabian Kuger for the DARWIN collaboration — Albert-Ludwigs-Universität, Freiburg, Germany

DARWIN

The DARWIN observatory is a proposed next-generation experiment to search for particle dark matter and other rare processes of nuclear or astrophysical origin. Its time projection chamber will instrument 40 t of natural liquid xenon containing about 3.6 t of 136Xe. The combination of ultra low background levels, very good energy resolution and large target mass predestines DARWIN to search for the neutrionless double beta decay of 136Xe.

We present a Monte Carlo simulation study of the background and event topologies resulting in a projected half-life sensitivity of 2.4 × 1027 yr after 10 yr of DARWIN operation, a comparable science reach to dedicated double beta decay experiments using xenon targets enriched in 136Xe.
