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 …

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 …

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 …

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 …

Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of
external electric and magnetic fields. We discuss this phenomenon with a particular focus on …

Polarization measurements of thermal radiation from magnetic white dwarf (MWD) stars
have been proposed as a probe of axion-photon mixing. The radiation leaving the surface of …

Two of the most pressing questions in physics are the microscopic nature of the dark matter
that comprises 84% of the mass in the Universe and the absence of a neutron electric dipole …

The axion is a light pseudoscalar particle postulated to solve issues with the Standard
Model, including the strong CP problem and the origin of dark matter. In recent years, there …

Light primordial black holes may comprise a dominant fraction of the dark matter in our
Universe. This paper critically assesses whether planned and future gravitational wave …
