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…
Discriminating Dark Matter Origins with Directional Detection
Nicole F. Bell, Chiara Lisotti, Jayden L. Newstead +2
Scenarios where dark matter is boosted to relativistic velocities provide a promising probe of sub-GeV dark matter. Cosmic-ray upscattered and supernova-produced dark matter genera…
Directional recoil detection for CEvNS measurements with light nuclei at the Spallation Neutron Source
Ciaran A. J. O'Hare, Anirudh Chandra Shekar, Chiara Lisotti +5
The coherent elastic scattering of neutrinos on nuclei, also known as CEvNS, has been studied for several years by the COHERENT program of experiments using neutrinos from stopped-…

The neutron portal operator provides a theoretically motivated connection between the visible and dark sectors and features in several well-studied asymmetric dark matter models. T…
Nuclear and electron scattering by neutrinos and dark matter in condensed systems
James B. Dent, Barry A. Friedman, Jayden L. Newstead +1
Low-threshold dark matter detectors, in particular cryogenic detectors based on dielectric materials, are among the best tools for probing sub-GeV dark matter masses. In the coming…

Detailed nuclear structure calculations for coherent elastic neutrino-nucleus scattering
Raghda Abdel Khaleq, Jayden L. Newstead, Cedric Simenel +1
Any discovery of `new physics' in the neutrino sector first requires a precise prediction of the expected Standard Model cross section. Currently, Coherent Elastic neutrino-Nucleus…

The detectability of light dark matter in direct detection experiments is limited by the small kinetic energy of the recoiling targets. Thus, scenarios where dark matter is boosted…
