Sub-GeV Dark Matter Under Pressure from Direct Detection
Andrew Cheek, Pablo Figueroa, Gonzalo Herrera +1
The DAMIC-M collaboration recently reported impressive bounds on sub-GeV dark matter, robustly testing both thermal and non-thermal models for the very first time. In this work we…

Dark photon dark matter from flattened axion potentials
Hong-Yi Zhang, Paola Arias, Andrew Cheek +3
Dark photons can be resonantly produced in the early universe via their coupling to an oscillating axion field. However, this mechanism typically requires large axion--dark photon…

Testing the dark origin of neutrino masses with oscillation experiments
Andrew Cheek, Luca Visinelli, Hong-Yi Zhang
The origin of neutrino masses remains unknown to date. One popular idea involves interactions between neutrinos and ultralight dark matter, described as fields or particles with ma…
