Leggett-Garg Inequality Violation in Muon Experiments
Brian Batell, Morgan Cassidy, Kun Cheng
We present the first study of Leggett-Garg inequality violation in polarized muon spin precession. We formulate a procedure to reconstruct temporal correlators of the longitudinal…
Majoron Dark Matter, High-Scale Seesaw, and Leptogenesis
Brian Batell, Arnab Dasgupta, Swapnil Dutta +1
We study the cosmology and observational probes of majoron dark matter in a high-scale seesaw framework with spontaneously broken lepton number. Right-handed neutrinos naturally ge…
Phasing out Dark Matter Isocurvature with Thermal Misalignment
Brian Batell, Akshay Ghalsasi, Subhajit Ghosh +1
Thermal misalignment provides an alternative to the standard misalignment mechanism for the cosmological production of scalar dark matter. In this framework, feeble couplings to pa…
Review of Neutral Naturalness
Brian Batell, Matthew Low, Ethan T. Neil +1
The hierarchy between the mass parameter of the Higgs boson and larger mass scales becomes ever more puzzling as experiments explore higher energies. Neutral naturalness is the umb…
-incidental -naturalness
Brian Batell, Akshay Ghalsasi, Wenjie Huang +1
-naturalness is a novel solution to the electroweak hierarchy problem which posits copies of the Standard Model with varying Higgs mass-squared parameters. Reheating proceed…
Letter of Intent: The Forward Physics Facility
Luis A. Anchordoqui, John K. Anders, Akitaka Ariga +111
The Forward Physics Facility (FPF) is a proposed extension of the HL-LHC program designed to exploit the unique scientific opportunities offered by the intense flux of high energy…
