Dark Matter Nuclear Magnetic Resonance is Sensitive to Dark Photons and the Axion-Photon Coupling
Carl Beadle, Sebastian A. R. Ellis, Jacob M. Leedom +1
We demonstrate that nuclear magnetic resonance based searches for dark matter (DM) have intrinsic and powerful sensitivity to dark photons and the axion-photon coupling. The reason…
Probing the UV with IR Axion Dark Matter Experiments
Jacob M. Leedom, Serah Moldovsky, Hitoshi Murayama
There is an ongoing and future experimental program searching for axions as both extensions of the Standard Model and as candidates for the observed dark matter. In this paper, we…
Implications of Protecting the QCD Axion in the Dual Description
Gongjun Choi, Jacob Leedom
The QCD axion can be be formulated in a dual description as a massive 2-form field. In this picture, the QCD axion quality problem translates into the question if there are additio…
On the Sensitivity of Spin-Precession Axion Experiments
Jeff A. Dror, Stefania Gori, Jacob M. Leedom +1
A leading direction in the hunt for axion dark matter is to search for its influence on nuclear spins. The detection scheme involves polarizing a sample of nuclei within a strong s…
Cosmological Tension of Ultralight Axion Dark Matter and its Solutions
Jeff A. Dror, Jacob M. Leedom
A number of proposed and ongoing experiments search for axion dark matter with a mass nearing the limit set by small scale structure (). We con…
QCD Axion Dark Matter from a Late Time Phase Transition
Keisuke Harigaya, Jacob M. Leedom
We investigate the possibility that the Peccei-Quinn phase transition occurs at a temperature far below the symmetry breaking scale. Low phase transition temperatures are typical i…
Unified Models of the QCD Axion and Supersymmetry Breaking
Keisuke Harigaya, Jacob Leedom
Similarities between the gauge meditation of supersymmetry breaking and the QCD axion model suggest that they originate from the same dynamics. We present a class of models where s…
