Axiverse Lampposts
Masha Baryakhtar, David Cyncynates, Ella Henry
The string axiverse predicts a unique connection between the high scales approachable only through theory and the low energies within reach of experimental verification: a multitud…
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…
Scalar relics from the hot Big Bang
David Cyncynates, Olivier Simon
In this Letter, we motivate the fact that couplings between a scalar field and the Standard Model with strengths relative to gravity yield the total…
Minimal targets for dilaton direct detection
David Cyncynates, Olivier Simon
Fifth force and equivalence principle tests search for new interactions by precisely measuring forces between macroscopic collections of atoms and molecules and their properties un…
Experimental targets for dark photon dark matter
David Cyncynates, Zachary J. Weiner
Ultralight dark photon dark matter features distinctive cosmological and astrophysical signatures and is also supported by a burgeoning direct-detection program searching for its k…
Detectable and defect-free dark photon dark matter
David Cyncynates, Zachary J. Weiner
Ultralight dark photons are compelling dark matter candidates, but their allowed kinetic mixing with the Standard Model photon is severely constrained by requiring that the dark ph…
