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…
NASDUCK': Laboratory Limits on Ultralight Dark-Photon Dark Matter with Null-Axis Magnetometry
Joel Barir, Itay M. Bloch, Yair Goldszeft +4
The dark photon is a well-motivated ultralight dark-matter candidate that may couple to the Standard Model through kinetic mixing. We search for dark-photon dark matter in the mass…
Earth-Scattering Induced Modulation in Low-Threshold Dark Matter Experiments
Xavier Bertou, Ansh Desai, Timon Emken +3
Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth before reaching and scattering in a detector. This induces a modulation in…
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-…
Constraints on axion-like dark matter from a SERF comagnetometer
Itay M. Bloch, Roy Shaham, Yonit Hochberg +3
Ultralight axion-like particles are well-motivated relics that might compose the cosmological dark matter and source anomalous time-dependent magnetic fields. We report on terrestr…
Primordial Black Holes from Supercooled Phase Transitions
Yann Gouttenoire, Tomer Volansky
Cosmological first-order phase transitions (1stOPTs) are said to be strongly supercooled when the nucleation temperature is much smaller than the critical temperature. These are of…
