Charge Trap Analysis in a SENSEI Skipper-CCD: Understanding Low-Energy Backgrounds in Rare-Event Searches
Agustin Brusco, Bruno Sivilotti, Ana M. Botti +14
Skipper Charge-Coupled Devices (Skipper-CCDs) are ultra-low-threshold detectors capable of detecting energy deposits in silicon at the eV scale. Increasingly used in rare-event sea…

Earth-Scattering Induced Modulation in Low-Threshold Dark Matter Experiments
Xavier Bertou, Ansh Desai, Timon Emken +3
Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth before reaching and scattering in a detector. This induces a modulation in…

A Neural Network Enhanced Born Approximation for Inverse Scattering
Ansh Desai, Jonathan Ma, Timo Lahivaara +1
Time-harmonic acoustic inverse scattering concerns the ill-posed and nonlinear problem of determining the refractive index of an inaccessible, penetrable scatterer based on far fie…
