DMRadio-GUT: A Future Search For GUT-scale QCD Axion Dark Matter
ORAL
Abstract
We introduce DMRadio-GUT, a future search for electromagnetic coupling to axion dark matter in the 400 peV-125 neV mass range, with sensitivity to GUT-scale QCD axion models. DMRadio-GUT is a challenging, long-term experiment that will build upon the techniques developed from the preceding DMRadio-50L and DMRadio-m$^{\mathrm{3}}$ campaigns. The search will take advantage of emerging and future developments in large, high-field magnets, high-Q superconducting lumped-element resonators, and electromagnetic quantum metrology in the kHz and MHz frequency ranges. In this talk, we overview the technological research and development needed to enable a GUT-scale QCD axion dark matter search with DMRadio-GUT.
