Description
The MAJORANA DEMONSTRATOR is a neutrinoless double-beta decay experiment operating at the 4850' level of the Sanford Underground Research Facility that uses modular arrays of enriched, 76Ge detectors in an ultra-low background environment. The DEMONSTRATOR has a low energy program that is capable of probing a variety of exotic keV-scale physics; it has recently produced limits on generic bosonic dark matter that come in two weakly coupling varieties, vector and pseudoscalar (axion-like). These particles would manifest as low energy peaks at their rest mass in the detector spectrum. I describe recent efforts in the MAJORANA DEMONSTRATOR's ongoing bosonic dark matter campaign, specifically improving the limits on the relevant coupling parameters.
