Simulation-Informed High-Velocity Dark Matter in the Effective Theory of Direct Detection
Xiuyuan Zhang, Gonzalo Herrera, Andreas Thoyas +1
The interpretation and reach of direct detection (DD) experiments depend sensitively on the local dark matter (DM) velocity distribution, particularly its high-velocity tail. This…
Mineral Detection of Neutrinos and Dark Matter 2026 Proceedings
Alexey Elykov, Patrick Stengel, Natsue Abe +81
The fourth "Mineral Detection of Neutrinos and Dark Matter" (MDvDM'26) meeting was held April 14-17, 2026 in Karlsruhe, Germany, hosted by the Institute for Astroparticle Physics (…
Negative energies and the breakdown of bulk geometry
John Preskill, Mykhaylo Usatyuk, Shreya Vardhan
One central question in quantum gravity is to understand how and why predictions from semiclassical gravity can break down in regimes with low spacetime curvature. One diagnostic o…
CMB Spectral Distortions from Resonant Conversions in Atomic Dark Sectors
Duncan K. Adams, Jared Barron, Bryce Cyr +1
Dark sectors consisting of atomic constituents (electrons, protons, and photons) offer a well-motivated extension to the Standard Model while providing multiple avenues for phenome…
Darkness in the Crust: Searching for the truly "Dark" Subhalos with Paleo-detectors
Xiuyuan Zhang, Lina Necib, Denis Erkal
Low-mass dark matter (DM) subhalos are pivotal in understanding the small-scale structure of the universe, thereby offering a sensitive method to discriminate between different cos…
Searching for GeV Gamma-Ray Polarization and Axion-Like Particles with AMS-02
Xiuyuan Zhang, Yi Jia, Tracy R. Slatyer
We study the detectability of GeV-band gamma-ray polarization with the AMS-02 experiment and its proposed successor AMS-100, from Galactic and extragalactic sources. Characterizing…
