Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

We improve the current upper bound on the axion-photon coupling derived from stellar
evolution using the R 2 parameter, the ratio of stellar populations on the Asymptotic Giant …

The main mechanism responsible for Axion-Like-Particle (ALP) production in the early
universe is the so-called misalignment mechanism. Three regimes have been investigated …

In the scenario in which QCD axion dark matter is produced after inflation, the Universe is
populated by large inhomogeneities on very small scales. Eventually, these fluctuations will …

Axions and axionlike particles (ALPs) are some of the most popular candidates for dark
matter, with several viable production scenarios that make different predictions. In the …

We present a proposal for a new experiment, the FINUDA magnet for Light Axion SearcH
(FLASH), a large resonant-cavity haloscope in a high static magnetic field which is planned …

With axions now a primary candidate for dark matter, understanding their indirect
astrophysical signatures is of paramount importance. Key to this is the production of photons …

One of the promising new proposals to search for axions in astrophysical environments is to
look for narrow radio lines produced from the resonant conversion of axion dark matter …

Axions and axionlike particles are a prominent dark matter candidate, drawing motivation in
part from the axiverse of string theory. Axionlike particles can also arise as composite …

We establish new experiments to search for dark matter based on a model of a light scalar
field with a dilaton-like coupling to the electromagnetic field, which is strongly motivated by …
