For Whom the Xenon Recoils: Magnetic Inelastic Dark Baryons
Pouya Asadi, Austin Batz, Patrick J. Fox +2
We develop a theory of a dark baryon dark matter candidate that interacts with nuclei dominantly through inelastic scattering mediated by a transition magnetic dipole operator. Mod…

Lepton Flavor Violation: From Muon Decays to Muon Colliders
Pouya Asadi, Hengameh Bagherian, Katherine Fraser +2
We investigate the unique potential of a high-energy muon collider to probe lepton-flavor-violating signals arising from physics beyond the Standard Model (SM). Low-energy, precisi…
Strong CP from a Hidden Chiral Condensate
Csaba Csáki, Samuel Homiller, Taewook Youn
Models which solve the strong CP problem by employing discrete spacetime symmetries generically suffer fine-tuning and quality problems. We demonstrate that these issues are greatl…
Stopping Dark Mesons in Their Tracks with Long-Lived Particle and Resonant Signatures
Pouya Asadi, Austin Batz, Elias Bernreuther +3
Dark sectors with confining gauge interactions can provide both simple dark matter candidates and striking signals at colliders. We recast Large Hadron Collider searches for two di…

The sensitivity of electron EDM experiments has been increasing at a rapid pace, and could yield indications of new physics in the coming decade. An intriguing possibility is that…
Relevance of one-loop SMEFT matching in the 2HDM
Supratim Das Bakshi, Sally Dawson, Duarte Fontes +1
The Two-Higgs Doublet Model (2HDM) is a well understood alternative to the Standard Model of particle physics. If the new particles included in the 2HDM are at an energy scale much…
Zero Modes of Massive Fermions Delocalize from Axion Strings
Hengameh Bagherian, Katherine Fraser, Samuel Homiller +1
Massless chiral excitations can arise from the interactions between a fermion and an axion string, propagating along the string and allowing it to superconduct. The properties of t…
Wrinkles in the Froggatt-Nielsen Mechanism and Flavorful New Physics
