Description
The MAJORANA DEMONSTRATOR is currently searching for neutrinoless double-beta decay in $^{76}$Ge and will demonstrate the feasibility to deploy a tonne-scale experiment in a phased and modular fashion. It consists of two modular arrays of natural and $^{76}$Ge-enriched germanium detectors totaling 44.1 kg, of which 29.7 kg is enriched, located at the 4850' level of the Sanford Underground Research Facility in Lead, South Dakota, USA. The low-backgrounds and low thresholds (< 1 keV) achieved by the DEMONSTRATOR allow for additional rare-event searches at low-energies, e.g. searches for low-mass WIMPs, bosonic dark matter, and solar axions. In this work, we will present results and ongoing efforts related to these rare-event searches and discuss the future reach of MAJORANA.
Summary
Searches for low-mass WIMPs, bosonic dark matter, and solar axions with the MAJORANA DEMONSTRATOR.
