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)
D. Mondal, W. Baker, M. Chaudhuri +19
As cryogenic detectors push toward ever-lower energy thresholds, their sensitivity is increasingly constrained by a persistent low-energy background known as the low-energy excess…
Model-independent searches of new physics in DARWIN with a semi-supervised deep learning pipeline
J. Aalbers, K. Abe, M. Adrover +231
We present a novel deep learning pipeline to perform a model-independent, likelihood-free search for anomalous (i.e., non-background) events in the proposed next generation multi-t…
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…
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-…
