Erratum to: Sensitivity of the DARWIN observatory to the neutrinoless double be...
Agostini, F.; Maouloud, S. E. M. Ahmed; Althueser, L.; Amaro, F. D.; Antunovic, B.; Aprile, E.; Baudis, L.; Baur, D.; Biondi, Y.; Bismark, A.We correct an overestimation of the production rate of 137Xe 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 8B neutrinos, thus unproblematic at the LNGS depth. The projected half-life sensitivity for the neutrinoless double beta decay (0νββ) of 136Xe improves by 22% compared to the previously reported...
A next-generation liquid xenon observatory for dark matter and neutrino physics
Aalbers, J.; AbdusSalam, S. S.; Abe, K.; Aerne, V.; Agostini, F.; Ahmed Maouloud, S.; Akerib, D. S.; Akimov, D. Y.; Akshat, J.; Al Musalhi, A. K.The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon timeprojection chamber is the leading technology to cover the available parameter space for weakly interacting massive particles, while featuring extensive sensitivity to many alternative dark matter candidates. These detectors can also study neutrinos through neutrinol...

Agostini, F.; Maouloud, S. E. M. Ahmed; Althueser, L.; Amaro, F. D.; Antunovic, B.; Aprile, E.; Baudis, L.; Baur, D.; Biondi, Y.; Bismark, A.The DARWIN observatory is a proposed nextgeneration experiment to search for particle dark matter and for the neutrinoless double beta decay of 136Xe.Out of its 50 t total natural xenon inventory, 40 t will be the active target of a time projection chamber which thus contains about 3.6 t of 136Xe. Here, we show that its projected half-life sensitivity is 2.4 × 1027 years, using a fiducial volume of 5 t of natur...
Solar neutrino detection sensitivity in DARWIN via electron scattering
Aalbers, J.; Agostini, F.; Maouloud, S. E. M. Ahmed; Alfonsi, M.; Althueser, L.; Amaro, F. D.; Angevaare, J.; Antochi, V. C.; Antunovic, B.; Aprile, E.We detail the sensitivity of the proposed liquid xenon DARWIN observatory to solar neutrinos via elastic electron scattering. We find that DARWIN will have the potential to measure the fluxes of five solar neutrino components: pp, 7Be, 13N, 15O and pep. The precision of the 13N, 15O and pep components is hindered by the doublebeta decay of 136Xe and, thus, would benefit from a depleted target. A high-statistics...
