A High Efficiency Photon Veto for the Light Dark Matter eXperiment
Torsten Åkesson, Nikita Blinov, Lene Bryngemark +28
Fixed-target experiments using primary electron beams can be powerful discovery tools for light dark matter in the sub-GeV mass range. The Light Dark Matter eXperiment (LDMX) is de…
Dark matter search in a Beam-Dump eXperiment (BDX) at Jefferson Lab -- 2018 update to PR12-16-001
M. Battaglieri, A. Bersani, G. Bracco +122
This document complements and completes what was submitted last year to PAC45 as an update to the proposal PR12-16-001 "Dark matter search in a Beam-Dump eXperiment (BDX)" at Jeffe…
New Limits on Charged Dark Matter from Large-Scale Coherent Magnetic Fields
Albert Stebbins, Gordan Krnjaic
We study the interaction of an electrically charged component of the dark matter with a magnetized galactic interstellar medium (ISM) of (rotating) spiral galaxies. For the observe…
Electron Ionization via Dark Matter-Electron Scattering and the Migdal Effect
Daniel Baxter, Yonatan Kahn, Gordan Krnjaic
There are currently several existing and proposed experiments designed to probe sub-GeV dark matter (DM) using electron ionization in various materials. The projected signal rates…
Implications of BBN Bounds for Cosmic Ray Upscattered Dark Matter
Gordan Krnjaic, Samuel D. McDermott
We consider the Big Bang Nucleosynthesis (BBN) bounds on light dark matter whose cross section off nucleons is sufficiently large to enable acceleration by scattering off of cosmic…
Dark Radiation and Superheavy Dark Matter from Black Hole Domination
Dan Hooper, Gordan Krnjaic, Samuel D. McDermott
If even a relatively small number of black holes were created in the early universe, they will constitute an increasingly large fraction of the total energy density as space expand…
Constraining the Self-Interacting Neutrino Interpretation of the Hubble Tension
Nikita Blinov, Kevin J. Kelly, Gordan Krnjaic +1
Large, non-standard neutrino self-interactions have been shown to resolve the tension in Hubble constant measurements and a milder tension in the amplitude of matter fluc…
Proposal for gravitational direct detection of dark matter
Daniel Carney, Sohitri Ghosh, Gordan Krnjaic +1
The only coupling dark matter is guaranteed to have with the standard model is through gravity. Here we propose a concept for direct dark matter detection using only this gravitati…
Cosmology With a Very Light Gauge Boson
Miguel Escudero, Dan Hooper, Gordan Krnjaic +1
In this paper, we explore in detail the cosmological implications of an abelian gauge extension of the Standard Model featuring a light and weakly coupled . Such a sc…
