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…
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…
SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB
SENSEI Collaboration, Prakruth Adari, Itay M. Bloch +34
We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximat…
Low-Energy Compton Scattering in Materials
Rouven Essig, Yonit Hochberg, Yutaro Shoji +2
Low-energy Compton scattering is an important background for sub-GeV dark matter direct-detection and other experiments. Current Compton scattering calculations typically rely on a…
Fully ab-initio all-electron calculation of dark matter--electron scattering in crystals with evaluation of systematic uncertainties
Cyrus E. Dreyer, Rouven Essig, Marivi Fernandez-Serra +2
We calculate target-material responses for dark matter--electron scattering at the \textit{ab-initio} all-electron level using atom-centered gaussian basis sets. The all-electron e…
Confirmation of the spectral excess in DAMIC at SNOLAB with skipper CCDs
A. Aguilar-Arevalo, I. Arnquist, N. Avalos +69
We present results from a 3.25 kg-day target exposure of two silicon charge-coupled devices (CCDs), each with 24 megapixels and skipper readout, deployed in the DAMIC setup at SNOL…
SENSEI: Search for Millicharged Particles produced in the NuMI Beam
Liron Barak, Itay M. Bloch, Ana M. Botti +28
Millicharged particles appear in several extensions of the Standard Model, but have not yet been detected. These hypothetical particles could be produced by an intense proton beam…
Searching for millicharged particles with 1 kg of Skipper-CCDs using the NuMI beam at Fermilab
Santiago Perez, Dario Rodrigues, Juan Estrada +57
Oscura is a planned light-dark matter search experiment using Skipper-CCDs with a total active mass of 10 kg. As part of the detector development, the collaboration plans to build…
Skipper-CCD Sensors for the Oscura Experiment: Requirements and Preliminary Tests
Brenda A. Cervantes-Vergara, Santiago Perez, Juan Estrada +52
Oscura is a proposed multi-kg skipper-CCD experiment designed for a dark matter (DM) direct detection search that will reach unprecedented sensitivity to sub-GeV DM-electron intera…
EXCESS workshop: Descriptions of rising low-energy spectra
P. Adari, A. Aguilar-Arevalo, D. Amidei +303
Many low-threshold experiments observe sharply rising event rates of yet unknown origins below a few hundred eV, and larger than expected from known backgrounds. Due to the signifi…
Snowmass2021 Cosmic Frontier: The landscape of low-threshold dark matter direct detection in the next decade
Rouven Essig, Graham K. Giovanetti, Noah Kurinsky +90
The search for particle-like dark matter with meV-to-GeV masses has developed rapidly in the past few years. We summarize the science case for these searches, the recent progress,…
The Oscura Experiment
Alexis Aguilar-Arevalo, Fabricio Alcalde Bessia, Nicolas Avalos +41
The Oscura experiment will lead the search for low-mass dark matter particles using a very large array of novel silicon Charge Coupled Devices (CCDs) with a threshold of two electr…
SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD
Liron Barak, Itay M. Bloch, Ana Botti +22
We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the orig…
SENSEI: Direct-Detection Results on sub-GeV Dark Matter from a New Skipper-CCD
Liron Barak, Itay M. Bloch, Mariano Cababie +20
We present the first direct-detection search for eV-to-GeV dark matter using a new ~2-gram high-resistivity Skipper-CCD from a dedicated fabrication batch that was optimized for da…
Gaussian Processes, Median Statistics, Milky Way Rotation Curves
Hai Yu, Aman Singal, Jacob Peyton +2
We use the Iocco et al. (2015) compilation of 2,780 circular velocity measurements to analyze the Milky Way rotation curve. We find that the error bars for individual measurements…
