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 …

With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

We report the results from a haloscope search for axion dark matter in the 3.3–4.2 μ eV mass
range. This search excludes the axion-photon coupling predicted by one of the benchmark …

This report provides an extensive review of the experimental programme of direct detection
searches of particle dark matter. It focuses mostly on European efforts, both current and …

We review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

We review the landscape of QCD axion models. Theoretical constructions that extend the
window for the axion mass and couplings beyond conventional regions are highlighted and …

The dark photon is a massive hypothetical particle that interacts with the Standard Model by
kinetically mixing with the visible photon. For small values of the mixing parameter, dark …

This Letter reports on a cavity haloscope search for dark matter axions in the Galactic halo in
the mass range 2.81–3.31 μ eV. This search utilizes the combination of a low-noise …

Abstract The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting
the full scientific potential of the CERN's accelerator complex and scientific infrastructures …

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 …
