Dark Matter Investigation Using Double Beta Decay Experiments

Physical Sciences Forum, 2023
Nuclei that are unstable with respect to double beta decay are potentially interesting for a novel Dark Matter (DM) direct detection approach. In particular, a Majorana DM fermion inelastically scattering on a double beta unstable nucleus could stimulate

Neutrinoless double beta decay searches with the XENON dark matter experiment

, 2018
The XENON1T experiment is leading the sensitivity to spin-independent, elastic WIMP-nucleon scatters, excluding cross-sections down to 7.7·10−47 ^{−47} cm2 ^2 at a mass of 35 GeV/c2 ^2 (90% CL) with the first science run of 34 days.

A model of neutrino mass and dark matter with large neutrinoless double beta decay [PDF]

Journal of High Energy Physics, 2017
We propose a model where neutrino masses are generated at three loop order but neutrinoless double beta decay occurs at one loop. Thus we can have large neutrinoless double beta decay observable in the future experiments even when the neutrino masses are

Bound-state dark matter with Majorana neutrinos

Physics Letters B, 2019
We propose a simple scenario in which dark matter (DM) emerges as a stable neutral hadronic thermal relic, its stability following from an exact U(1)D symmetry.

Development and properties of cadmium and lead tungstate low-background scintillators for double beta decay experiments [PDF]

Ядерна фізика та енергетика, 2014
Methods of deep purification of natural and isotopically enriched cadmium (Cd, 106Cd, 116Cd), as well as of archaeological lead (archPb), to produce cadmium and lead tungstate crystal scintillators have been developed. The basic stages of development and

Neutrino meets ultralight dark matter: $\boldsymbol{0\nu\beta\beta}$ decay and cosmology [PDF]

, 2022
We explore the neutrinoless double beta ($0\nu \beta\beta$) decay induced by an ultralight dark matter field coupled to neutrinos. The effect on $0\nu\beta\beta$ decay is significant if the coupling violates the lepton number, for which the $\Delta L=2 ...

Sensitivity of the DARWIN observatory to the neutrinoless double beta decay of 136-Xe [PDF]

, 2020
DARWIN will be a direct dark matter detection experiment using a multi-ton liquid xenon time projection chamber at its core. With 50 tonnes of natural xenon, DARWIN will be designed to explore the entire experimentally accessible parameter space for ...

Potential of a next generation neutrinoless double beta decay experiment based on ZnMoO4 scintillating bolometers [PDF]

, 2012
The search for neutrinoless double β decay probes lepton number conservation with high sensitivity and investigates the neutrino nature and mass scale.

Investigation of light dark matter with 2 $$\beta $$ β decay experiments

, 2023
Nuclei that are unstable with respect to double beta decay are investigated in this work for a novel dark matter (DM) direct detection approach. In particular, the diagram responsible for the neutrinoless double beta decay can be considered for the ...
