A Thermal Relic Encyclopedia: Dark Matter Candidates Coupled to Quarks
Dan Hooper, Gordan Krnjaic, Tanner Trickle +1
Thermal freeze-out is a compelling framework for naturally generating the dark matter abundance. We systematically study a broad range of dark matter and mediator particle combinat…
LDMX -- The Light Dark Matter eXperiment
Torsten Akesson, Layan Alsaraya, Stephen Appert +116
The Light Dark Matter eXperiment (LDMX) is an electron fixed-target experiment optimized to search for sub-GeV dark matter production through the missing momentum signature. LDMX i…
X-rays from Inelastic Dark Matter Freeze-in
Gordan Krnjaic, David McKeen, Riku Mizuta +3
We study inelastic dark matter produced via freeze-in through a light mediator with a mass splitting below the electron-positron threshold. In this regime, the heavier dark matter…
Sensitivity of an Early Dark Matter Search using the Electromagnetic Calorimeter as a Target for the Light Dark Matter eXperiment
LDMX Collaboration, Torsten Åkesson, Elizabeth Berzin +53
The Light Dark Matter eXperiment (LDMX) is proposed to employ a thin tungsten target and a multi-GeV electron beam to carry out a missing momentum search for the production of dark…
Gamma-Rays and Gravitational Waves from Inelastic Higgs Portal Dark Matter
Dan Hooper, Gordan Krnjaic, Duncan Rocha +1
We explore a simple and predictive dark matter scenario involving a complex scalar field, , coupled to the Higgs portal with no additional field content. In the UV, the field po…
Testing Thermal-Relic Dark Matter with a Dark Photon Mediator
Gordan Krnjaic
In light of recent DAMIC-M results, we present the status of thermal-relic dark matter coupled to a kinetically-mixed dark photon . In the predictive "direct annihila…
dSphobic Dark Matter
Asher Berlin, Joshua W. Foster, Dan Hooper +1
We present a mechanism that allows thermal relic dark matter to annihilate efficiently in the Galactic Halo and in galaxy clusters, but not in the lower-velocity environments of dw…
Observing Dark Matter Decays to Gravitons via Graviton-Photon Conversion
David I. Dunsky, Gordan Krnjaic, Elena Pinetti
Since dark matter is only known to have gravitational interactions, it may plausibly decay to gravitons on cosmological timescales. Although such a scenario can be easily realized,…
Direct Detection of Ultralight Dark Matter via Charged Lepton Flavor Violation
Innes Bigaran, Patrick J. Fox, Yann Gouttenoire +4
We propose a dark matter direct-detection strategy using charged particle decays at accelerator-based experiments. If ultralight dark matter has a misalignment…
Testing the Froggatt-Nielsen Mechanism with Lepton Flavor and Number Violating Processes
Claudia Cornella, David Curtin, Gordan Krnjaic +1
The Froggatt-Nielsen (FN) mechanism offers an elegant explanation for the observed masses and mixings of Standard Model fermions. In this work, we systematically study FN models in…
