Spin-independent scattering of pseudoscalar-mediated dark matter
Nicole F. Bell, Giorgio Busoni, Peter Cox +6
Dark matter with pseudoscalar couplings provides a well-motivated scenario in which direct-detection signals are suppressed at tree level, since the scattering off nuclei is both s…
Exothermic and Endothermic Inelastic Dark Matter Interpretations at LZ: Sideband Constraints and Future Prospects
James B. Dent, Jayden L. Newstead
The LZ experiment has extended its nuclear-recoil search to 270 keV and reports a single nuclear-recoil-like event, LZ230616, at keV, in a region with negligible expected…
Dark matter energy exchange in stars orbiting supermassive black holes
Stephan A. Meighen-Berger, R. Andrew Gustafson, Nicole F. Bell +3
Stars on tight orbits around the supermassive black hole at the Galactic Center pass through regions where the dark matter~(DM) density may be strongly enhanced. We compute the orb…
Exploring Low Energy Excess in MINER with sapphire detectors using Convolutional Variational Autoencoder (CVAE)
