Background-Induced Forces from Quadratically Coupled Ultralight Dark Matter
Thomas Bouley, Xucheng Gan, Hailin Xu +1
Quadratically coupled ultralight scalar dark matter behaves as a coherent classical field whose interactions with matter can induce a composition-dependent force through the dark m…
DarkNESS: A skipper-CCD NanoSatellite for Dark Matter Searches
Phoenix Alpine, Samriddhi Bhatia, Ana M. Botti +16
The Dark matter Nanosatellite Equipped with Skipper Sensors (DarkNESS) deploys a recently developed skipper-CCD architecture with sub-electron readout noise in low Earth orbit (LEO…
Probing Millicharged Particles at an Electron Beam Dump with Ultralow-Threshold Sensors
Rouven Essig, Peiran Li, Zhen Liu +3
We propose to search for millicharged particles produced in high-intensity electron beam dumps using small ultralow-threshold sensors. As a concrete example, we consider a Skipper-…
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…
Constraints on Strongly-Interacting Dark Matter from the James Webb Space Telescope
Peizhi Du, Rouven Essig, Bernard J. Rauscher +1
Direct-detection searches for dark matter are insensitive to dark matter particles that have large interactions with ordinary matter, which are stopped in the atmosphere or the Ear…
Solar reflection of dark matter with dark-photon mediators
Timon Emken, Rouven Essig, Hailin Xu
We consider the scattering of low-mass halo dark-matter particles in the hot plasma of the Sun, focusing on dark matter that interact with ordinary matter through a dark-photon med…
