Cosmological limits on axions and axion-like particles
Davide Cadamuro
The axion is a pseudo-Nambu-Goldstone boson. It appears after the spontaneous breaking of the Peccei-Quinn symmetry, which was proposed to solve the strong-CP problem. Other pseudo…
WISPy Cold Dark Matter
Paola Arias, Davide Cadamuro, Mark Goodsell +3
Very weakly interacting slim particles (WISPs), such as axion-like particles (ALPs) or hidden photons (HPs), may be non-thermally produced via the misalignment mechanism in the ear…
Cosmological constraints on thermal relic axions and axion-like particles
Davide Cadamuro, Javier Redondo
Cosmological precision data can be used to set very strict constraints on Axions and Axion-like particles (ALPs) produced thermally in the big bang. We briefly review the known bou…
Cosmological bounds on pseudo Nambu-Goldstone bosons
Davide Cadamuro, Javier Redondo
We review the cosmological implications of a relic population of pseudo Nambu-Goldstone bosons (pNGB) with an anomalous coupling to two photons, often called axion-like particles (…
Cosmological bounds on sub-MeV mass axions
Davide Cadamuro, Steen Hannestad, Georg Raffelt +1
Axions with mass greater than 0.7 eV are excluded by cosmological precision data because they provide too much hot dark matter. While for masses above 20 eV the axion lifetime drop…
Hidden Photons from the Sun
Davide Cadamuro, Javier Redondo
A brief account of the phenomenon of photon oscillations into sub-eV mass hidden photons is given and used to estimate the flux and properties of these hypothetical particles from…
