Fully ab-initio all-electron calculation of dark matter-electron scattering in crystals with evaluation of systematic uncertainties

CE Dreyer, R Essig, M Fernandez-Serra, A Singal… - Physical Review D, 2024 - APS
We calculate target-material responses for dark matter–electron scattering at the ab initio all-
electron level using atom-centered Gaussian basis sets. The all-electron effects enhance the …

Skipper-CCDs: Current applications and future

BA Cervantes-Vergara, S Perez, JC D'Olivo… - Nuclear Instruments and …, 2023 - Elsevier
This work briefly discusses the potential applications of the Skipper-CCD technology in
astronomy and reviews its current use in dark matter and neutrino experiments. An overview …

The Migdal effect in semiconductors for dark matter with masses below∼ 100 MeV

KV Berghaus, A Esposito, R Essig… - Journal of High Energy …, 2023 - Springer
A bstract Dark matter scattering off a nucleus has a small probability of inducing an
observable ionization through the inelastic excitation of an electron, called the Migdal effect …

Resonant pseudo-Dirac dark matter as a sub-GeV thermal target

N Brahma, S Heeba, K Schutz - Physical Review D, 2024 - APS
Dark matter (DM) could be a pseudo-Dirac thermal relic with a small mass splitting that is
coupled off diagonally to a kinetically mixed dark photon. This model, particularly in the sub …

Neutrino fog for dark matter-electron scattering experiments

B Carew, AR Caddell, TN Maity, CAJ O'Hare - Physical Review D, 2024 - APS
The search for sub-GeV dark matter via scattering on electrons has ramped up in the last few
years. Like in the case of dark matter scattering on nuclei, electron-recoil-based searches …

Direct detection of light dark matter charged under a symmetry

P Figueroa, G Herrera, F Ochoa - Physical Review D, 2024 - APS
A possible extension of the Standard Model able to explain the recent measurement of the
anomalous magnetic moment of the muon consists in adding a gauged U (1) L μ-L τ …

[HTML][HTML] Some progress & challenges for the direct-detection of sub-GeV dark matter

R Essig - Nuclear Physics B, 2024 - Elsevier
In this contribution to the special issue on the Nobel Symposium on Dark Matter (NS 182), I
review some recent theoretical and experimental progress, as well as some current …

Direct detection of the millicharged background

E Iles, S Heeba, K Schutz - arxiv preprint arxiv:2407.21096, 2024 - arxiv.org
We show that dark matter direct detection experiments are sensitive to the existence of
particles with a small effective charge (for instance, via couplings to a kinetically mixed, low …

RK Leane, S Shin, L Yang, G Adhikari… - arxiv preprint arxiv …, 2022 - arxiv.org
Intriguing signals with excesses over expected backgrounds have been observed in many
astrophysical and terrestrial settings, which could potentially have a dark matter origin …
