New physics in multi-lepton tau decays
Yohei Ema, Patrick J. Fox, Matheus Hostert +4
Dark particles with lepton-flavor-violating couplings to the tau lepton can induce rare neutrinoless decays with large final state multiplicities. We study models where transit…
Radio Killed the Axion Star: Constraining Axion Properties with Radio Telescopes
Patrick J. Fox, Neal Weiner, Huangyu Xiao
Axion dark matter or any ultralight bosonic dark matter can go through Bose-Einstein condensation due to the large phase density, leading to the formation of axion stars or soliton…
Long-lived Axion-Like Particles from Tau Decays
Yohei Ema, Patrick J. Fox, Matheus Hostert +4
Axion-like particles (ALPs) are well-motivated examples of light, weakly coupled particles in theories beyond the Standard Model. In this work, we study long-lived ALPs coupled exc…
Direct Detection of Ultralight Dark Matter via Charged Lepton Flavor Violation
Innes Bigaran, Patrick J. Fox, Yann Gouttenoire +4
We propose a dark matter direct-detection strategy using charged particle decays at accelerator-based experiments. If ultralight dark matter has a misalignment…
Muon-induced baryon number violation
Patrick J. Fox, Matheus Hostert, Tony Menzo +2
The search for charged-lepton flavor violation in muon capture on nuclei is a powerful probe of heavy new physics. A smoking gun signal for conversion is a monochr…
Axion Stars: Mass Functions and Constraints
Jae Hyeok Chang, Patrick J. Fox, Huangyu Xiao
The QCD axion and axion-like particles, as leading dark matter candidates, can also have interesting implications for dark matter substructures if the Peccei-Quinn symmetry is brok…
Earth-Catalyzed Detection of Magnetic Inelastic Dark Matter with Photons in Large Underground Detectors
Joshua Eby, Patrick J. Fox, Graham D. Kribs
Inelastic dark matter with moderate splittings, keV, can upscatter to an excited state in the Earth, with the excited state subsequently…
Dark Matter Self-Interactions and Light Force Carriers
Matthew R. Buckley Patrick J. Fox
Recent observations from PAMELA, FERMI, and ATIC point to a new source of high energy cosmic rays. If these signals are due to annihilating dark matter, then the annihilation cross…
Reheating Metastable O'Raifeartaigh Models
Nathaniel J. Craig, Patrick J. Fox, Jay G. Wacker
In theories with multiple vacua, reheating to a temperature greater than the height of a barrier can stimulate transitions from a desirable metastable vacuum to a lower energy stat…
Supersplit Supersymmetry
P. J. Fox, D. E. Kaplan, E. Katz +5
The possible existence of an exponentially large number of vacua in string theory behooves one to consider possibilities beyond our traditional notions of naturalness. Such an appr…
