Long-Lived Charge Trap Characterization for Rare-Event Searches with Skipper-CCDs
Ansh Desai, Ana M. Botti, Brenda A. Cervantes-Vergara +9
Skipper Charge-Coupled Devices (Skipper-CCDs) are detectors with sub-electron resolution, allowing them to play a critical role in rare-event searches. A major challenge in experim…
Nuclear Recoil Migdal Effect in Liquid Xenon Dark Matter Experiments
Jingke Xu, Jeonghwa Kim, Duncan Adams +3
The Migdal effect predicts that a nuclear recoil can be accompanied by detectable atomic ionization or excitation signals, even at the low energies expected from interactions of su…
Characterization of Spurious Charge in SENSEI Skipper-CCDs
Yikai Wu, Ansh Desai, Sho Uemura +16
Skipper Charge-Coupled Devices (Skipper-CCDs) are a leading technology in the search for sub-GeV dark matter and coherent elastic neutrino-nucleus scattering. A key background for…
All-electron dark matter-electron scattering with random-phase approximation dielectric screening and local field effects
Cyrus Dreyer, Rouven Essig, Marivi Fernandez-Serra +2
Accurate predictions for dark matter-electron scattering in solids require an all-electron treatment together with a faithful description of dielectric screening beyond simple appr…
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…
SENSEI: A Search for Diurnal Modulation in sub-GeV Dark Matter Scattering
Itay M. Bloch, Ana M. Botti, Mariano Cababie +28
Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth's atmosphere and crust before reaching an underground detector. This Earth-…
Low-Energy Backgrounds in Solid-State Phonon and Charge Detectors
Daniel Baxter, Rouven Essig, Yonit Hochberg +5
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 advance…
Probing Millicharged Particles at an Electron Beam Dump with Ultralow-Threshold Sensors
Rouven Essig, Peiran Li, Zhen Liu +3
We propose to search for millicharged particles produced in high-intensity electron beam dumps using small ultralow-threshold sensors. As a concrete example, we consider a Skipper-…
SENSEI at SNOLAB: Single-Electron Event Rate and Implications for Dark Matter
Itay M. Bloch, Ana M. Botti, Mariano Cababie +27
We present results from data acquired by the SENSEI experiment at SNOLAB after a major upgrade in May 2023, which includes deploying 16 new sensors and replacing the copper trays t…
Collective excitations and low-energy ionization signatures of relativistic particles in silicon detectors
Rouven Essig, Ryan Plestid, Aman Singal
Solid-state detectors with a low energy threshold have several applications, including searches of non-relativistic halo dark-matter particles with sub-GeV masses. When searching f…
