SENSEI: First Direct-Detection Constraints on sub-GeV Dark Matter from a Surface Run
The SENSEI Collaboration, Michael Crisler, Rouven Essig +6
The Sub-Electron-Noise Skipper CCD Experimental Instrument (SENSEI) uses the recently developed Skipper-CCD technology to search for electron recoils from the interaction of sub-Ge…
New Constraints and Prospects for sub-GeV Dark Matter Scattering off Electrons in Xenon
Rouven Essig, Tomer Volansky, Tien-Tien Yu
We study in detail sub-GeV dark matter scattering off electrons in xenon, including the expected electron recoil spectra and annual modulation spectra. We derive improved constrain…
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…
Solar Neutrinos as a Signal and Background in Direct-Detection Experiments Searching for Sub-GeV Dark Matter With Electron Recoils
Rouven Essig, Mukul Sholapurkar, Tien-Tien Yu
Direct-detection experiments sensitive to low-energy electron recoils from sub-GeV dark matter (DM) interactions will also be sensitive to solar neutrinos via coherent neutrino-nuc…
2024 TASI Lectures: A Dark Matter Primer
Tien-Tien Yu
These notes are based on a sequence of 4 lectures delivered at the 2024 Theoretical Advanced Study Institute (TASI) and at the Università degli Studi di Padova. They are intended f…
On the relation between Migdal effect and dark matter-electron scattering in isolated atoms and semiconductors
Rouven Essig, Josef Pradler, Mukul Sholapurkar +1
A key strategy for the direct detection of sub-GeV dark matter is to search for small ionization signals. These can arise from dark matter-electron scattering or when the dark matt…
