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…
Search for reactor-produced millicharged particles with Skipper-CCDs at the CONNIE and Atucha-II experiments
Alexis A. Aguilar-Arevalo, Nicolas Avalos, Pablo Bellino +37
Millicharged particles, proposed by various extensions of the standard model, can be created in pairs by high-energy photons within nuclear reactors and can interact electromagneti…
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…
Unraveling Fano noise and partial charge collection effect in X-ray spectra below 1 keV
Dario Rodrigues, Mariano Cababie, Ignacio Gomez Florenciano +6
Fano noise, readout noise, and the partial charge collection (PCC) effect collectively contribute to the degradation of energy spectra in Charge Coupled Devices (CCD) measurements,…
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…
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…
Constraints on the electron-hole pair creation energy and Fano factor below 150 eV from Compton scattering in a Skipper-CCD
A. M. Botti, S. Uemura, G. Fernandez Moroni +9
Fully-depleted thick silicon Skipper-charge-coupled devices (Skipper-CCDs) are an important technology to probe neutrino and light-dark-matter interactions due to their sub-electro…
The Skipper CCD for low-energy threshold particle experiments above ground
Guillermo Fernandez Moroni, Fernando Chierchie, Javier Tiffenberg +11
We present experimental results using a single-electron resolution Skipper-CCD running above ground level to demonstrate the potential of this technology for its use in reactor neu…
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…
Absolute measurement of the Fano factor using a Skipper-CCD
Dario Rodrigues, Kevin Andersson, Mariano Cababie +11
Skipper-CCD can achieve deep sub-electron readout noise making possible the absolute determination of the exact number of ionized electrons in a large range, from 0 to above 1900 e…
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…
