Projected Sensitivity of DMRadio-m${}^3$: A Search for the QCD Axion Below $1\mu$eV

DMRadio Collaboration, L. Brouwer, S. Chaudhuri +31

The QCD axion is one of the most compelling candidates to explain the dark matter abundance of the universe. With its extremely small mass ($\ll 1\mathrm{eV}/c^2$), axion dark ma…
