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…

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…

Towards Measuring the CP-Violating Phase with Atmospheric Neutrinos

John F. Beacom, Nicole F. Bell, Matthew J. Dolan +2

We propose a new approach to measuring the CP-violating phase in neutrino mixing using atmospheric neutrinos, differing significantly from prior work. We develop an up-down flux ra…

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…

Dark Matter Induced Nucleon Decay Through the Neutron Portal

Nicole F. Bell, Peter Cox, Jayden L. Newstead +1

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…

Using neutron stars to probe dark matter charged under a symmetry

Nicole F. Bell, Giorgio Busoni, Avirup Ghosh

Kinetic heating of old cold neutron stars, via the scattering of dark matter with matter in the star, provides a promising way to probe the nature of dark matter interactions. We c…

Neutrino portals to MeV WIMPs with s-channel mediators

Nicole F. Bell, Matthew J. Dolan, Avirup Ghosh +1

Large-scale neutrino detectors currently under construction will have the unique ability to probe the annihilation of low-mass thermal-relic dark matter to neutrinos. This represen…

Enhancing DUNE's solar neutrino capabilities with neutral-current detection

Stephan A. Meighen-Berger, Jayden L. Newstead, John F. Beacom +2

We show that the Deep Underground Neutrino Experiment (DUNE) has the potential to make a precise measurement of the total active flux of 8B solar neutrinos via neutral-current (NC)…

Heavy Dark Matter in White Dwarfs: Multiple-Scattering Capture and Thermalization

Nicole F. Bell, Giorgio Busoni, Sandra Robles +1

We present an improved treatment for the scattering of heavy dark matter from the ion constituents of a white dwarf. In the heavy dark matter regime, multiple collisions are requir…

Thermalization and Annihilation of Dark Matter in Neutron Stars

Nicole F. Bell, Giorgio Busoni, Sandra Robles +1

The capture of dark matter, and its subsequent annihilation, can heat old, isolated neutron stars. In order for kinetic heating to be achieved, the captured dark matter must underg…

New Signal of Atmospheric Tau Neutrino Appearance: Sub-GeV Neutral-Current Interactions in JUNO

Stephan A. Meighen-Berger, John F. Beacom, Nicole F. Bell +1

We propose the first practical method to detect atmospheric tau neutrino appearance at sub-GeV energies, which would be an important test of oscillations and o…

Cosmic-ray dark matter confronted by constraints on new light mediators

Nicole F. Bell, Jayden L. Newstead, Iman Shaukat-Ali

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…
