On the Run from the Dark Side of the Muon
Pouya Asadi, Austin Batz, Samuel Homiller +1
We present an analysis strategy for probing physics beyond the Standard Model via modifications to the parton distribution functions (PDFs) in a muon beam, which measurably alter t…
Early Universe Constraints on Variations in Fundamental Constants Induced by Ultralight Scalar Dark Matter
Subhajit Ghosh, Kimberly K. Boddy, Tien-Tien Yu
We study the cosmological impact of ultralight dark matter (ULDM) with a quadratic coupling to Standard Model particles. In addition to the suppression of small-scale power from UL…
Simplified Spin Dependence in Dark Matter Direct Detection
Pierce Giffin, Benjamin Lillard, Pankaj Munbodh +1
The interactions of dark matter with Standard Model particles can be systematically studied in the language of effective field theories. We investigate dark matter interactions wit…
Fermion-Portal Dark Matter at a High-Energy Muon Collider
Pouya Asadi, Samuel Homiller, Aria Radick +1
In this work, we provide a comprehensive study of fermion-portal dark matter models in the freeze-in regime at a future muon collider. For different possible non-singlet fermion po…
A Duet of Freeze-in and Freeze-out: Lepton-Flavored Dark Matter and Muon Colliders
Pouya Asadi, Aria Radick, Tien-Tien Yu
We study a Lepton-Flavored Dark Matter model and its signatures at a future Muon Collider. We focus on the less-explored regime of feeble dark matter interactions, which suppresses…
