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-…
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…
Analytical approximations as close as desired to special functions
Aviv Orly
We present a method for constructing global analytical expressions that approximate a function over its entire range. These approximations not only mirror the original function as…
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…
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…
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,…
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…
