Technically Natural Baryogenesis with the QCD Axion
Pouya Asadi, David Cyncynates, Stefania Gori
The strong CP problem, dark matter, and the observed baryon abundance may all be connected dynamically through the QCD axion, though whether this connection is realized in Nature d…
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…
Rich Phenomenology from Simple Ingredients: A Review of Confining Dark Sectors
Pouya Asadi, Austin Batz, Graham D. Kribs
We review theories with confining dark sectors and their implications for dark matter, cosmology, phenomenology, and unsolved Standard Model puzzles. Models with new strongly-coupl…
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…
Quirks Live in Cool Universes
Pouya Asadi, Graham D. Kribs, Markus A. Luty
We demonstrate that cosmological observations place strong bounds on the reheat temperature of the Standard Model (SM) in minimal models of `quirks' -- heavy fermions…
Axiverse Baryogenesis
Pouya Asadi, David Cyncynates, Stefania Gori
The QCD axion may offer a unified origin for the baryon asymmetry and dark matter through axiogenesis. However, in the minimal QCD axion scenario, axiogenesis either underproduces…
MuCol Milestone Report No. 7: Consolidated Parameters
Rebecca Taylor, Antoine Chancé, Dario Augusto Giove +459
This document is comprised of a collection of consolidated parameters for the key parts of the muon collider. These consolidated parameters follow on from the October 2024 Prelimin…
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…
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…
Genesis of baryon and dark matter asymmetries through ultraviolet scattering freeze-in
Pouya Asadi, Marianne Moore, David E. Morrissey +1
We introduce a new mechanism for the simultaneous generation of baryon and dark matter asymmetries through ultraviolet-dominated freeze-in scatterings. The mechanism relies on heav…
The Muon Collider
Carlotta Accettura, Simon Adrian, Rohit Agarwal +450
Muons offer a unique opportunity to build a compact high-energy electroweak collider at the 10 TeV scale. A Muon Collider enables direct access to the underlying simplicity of the…
Design Initiative for a 10 TeV pCM Wakefield Collider
Spencer Gessner, Jens Osterhoff, Carl A. Lindstrøm +198
This document outlines a community-driven Design Study for a 10 TeV pCM Wakefield Accelerator Collider. The 2020 ESPP Report emphasized the need for Advanced Accelerator R\&D, and…
Noble Dark Matter: Surprising Elusiveness of Dark Baryons
Pouya Asadi, Austin Batz, Graham D. Kribs
Dark matter could be a baryonic composite of strongly-coupled constituents transforming under SU(2). We classify the SU(2) representations of baryons in a class of simple c…
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…
MuCol Milestone Report No. 5: Preliminary Parameters
Carlotta Accettura, Simon Adrian, Rohit Agarwal +391
This document is comprised of a collection of updated preliminary parameters for the key parts of the muon collider. The updated preliminary parameters follow on from the October 2…
Direct Detection of Dark Baryons Naturally Suppressed by -parity
Pouya Asadi, Graham D. Kribs, Chester J. Hamilton Mantel
We identify symmetries in a broad class of vector-like confining dark sectors that forbid the leading electromagnetic moments that would ordinarily mediate dark baryon scattering w…
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…
Wrinkles in the Froggatt-Nielsen Mechanism and Flavorful New Physics
Pouya Asadi, Arindam Bhattacharya, Katherine Fraser +2
When the Froggatt-Nielsen mechanism is used to explain the Standard Model flavor hierarchy, new physics couplings are also determined by the horizontal symmetry. However, additiona…
Towards a Muon Collider
Carlotta Accettura, Dean Adams, Rohit Agarwal +294
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions a…
Chiral Nelson--Barr Models: Quality and Cosmology
Pouya Asadi, Samuel Homiller, Qianshu Lu +1
It was recently shown that domain walls from the spontaneous breaking of CP symmetry are exactly stable, and must be inflated away to recover a viable cosmology. We investigate the…
Quantum Entanglement and the Thermal Hadron
Pouya Asadi, Varun Vaidya
This paper tests how effectively the bound states of strongly interacting gauge theories are amenable to an emergent description as a thermal ensemble. This description can be deri…
Oblique Lessons from the Mass Measurement at CDF II
Pouya Asadi, Cari Cesarotti, Katherine Fraser +2
The CDF collaboration recently reported a new precise measurement of the boson mass with a central value significantly larger than the SM prediction. We explore the effec…
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
J. Aalbers, K. Abe, V. Aerne +591
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…
Glueballs in a Thermal Squeezeout Model
Pouya Asadi, Eric David Kramer, Eric Kuflik +2
It has been shown that a first order confinement phase transition can drastically change the relic dark matter abundance in confining dark sectors with only heavy dark quarks. We s…
