Auditing anapole dark matter: the limits of model independence in dark matter effective field theory
Duncan K. Adams, Jared Barron, Megan H. McDuffie
Effective field theory is a powerful tool for studying the low-energy behavior of dark sector models without explicit dependence on the high-energy physics. However, bottom-up EFT…
The Migdal effect in Semiconductors for the Effective Field Theory of Dark Matter Direct Detection
Kim V. Berghaus, Rouven Essig, Megan H. McDuffie
The Migdal effect in semiconductors, prompt ionization from a primary nuclear scattering event, can be described across all kinematic regimes using an effective field theory that e…
Pushing the Limits of Atomic Dark Matter: First-Principles Recombination Rates and Cosmological Constraints
Jared Barron, Rouven Essig, Megan H. McDuffie +2
Minimal atomic dark matter with its distinctive cooling mechanisms offers an instructive framework for understanding the potential impact of dark matter on small-scale structure fo…
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-…
