Erratum to: Sensitivity of the DARWIN observatory to the neutrinoless double beta decay of 136Xe
We correct an overestimation of the production rate of 137 Xe in the DARWIN detector operated at LNGS. This formerly dominant intrinsic background source is now at a level similar to the irreducible background from solar 8 B neutrinos, thus unproblematic at the LNGS depth. The projected half-life se...

Summary: | We correct an overestimation of the production rate of

Xe in the DARWIN detector operated at LNGS. This formerly dominant intrinsic background source is now at a level similar to the irreducible background from solar
