Low-Energy Backgrounds in Solid-State Phonon and Charge Detectors
read the original abstract
Solid-state phonon and charge detectors probe the scattering of weakly interacting particles, such as dark matter and neutrinos, through their low recoil thresholds. Recent advancements have pushed sensitivity to eV-scale energy depositions, uncovering previously-unseen low-energy excess backgrounds. While some arise from known processes such as thermal radiation, luminescence, and stress, others remain unexplained. This review examines these backgrounds, their possible origins, and parallels to low-energy effects in solids. Their understanding is essential for interpreting particle interactions at and below the eV-scale.

Prospect of the NUCLEUS Experiment at Chooz for Coherent Elastic Neutrino-Nucleus Scattering and New Physics Searches
Assuming the low-energy background can be eliminated, a 7-gram NUCLEUS detector at Chooz is projected to see coherent neutrino-nucleus scattering at 4.7σ in one year and to set competitive bounds on new neutrino interactions.

Light Dark Matter Search with 7.8 Tonne-Year of Ionization-Only Data in XENONnT
An S2-only analysis of 7.83 tonne-years of XENONnT data finds no dark matter excess and sets 90% CL limits, e.g. 6.0e-45 cm^2 for spin-independent scattering at 5 GeV/c^2.

SENSEI: A Search for Diurnal Modulation in sub-GeV Dark Matter Scattering
No sidereal daily modulation is seen in SENSEI single-electron data; the 90% C.L. amplitude bound is 6.8 e−/g/day and sub-MeV dark-matter cross-section limits improve by about an order of magnitude.
