The Dark Dimension meets the Axiverse
Kevin Langhoff, Maria Ramos, Mario Reig
The paper studies how combining dark dimension models with an axiverse affects early‑universe cosmology, showing that freeze‑in production of Kaluza‑Klein axion and graviton towers…
How well can the QCD axion hide?
Sung Mook Lee, Maria Ramos, Fuensanta Vilches
Motivated UV frameworks generically predict the existence of multiple axion fields. Their interplay gives rise to novel collective phenomena - including level crossings and the for…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Resonant Landau-Zener Conversion In Multi-Axion Systems
David I. Dunsky, Claudio Andrea Manzari, Pablo QuÃlez +2
Multiple axions may emerge in the low-energy effective theory of Nature. Generically, the potentials describing these axion fields are non-diagonal, leading to mass mixing between…
Extra-dimensional axion patterns
Arturo de Giorgi, Maria Ramos
We study the parameter space of a bulk axion in flat and warped extra spacetime dimensions. We characterize in detail the regimes where no single KK mode is pro…
