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 …

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 …

The quantum chromodynamics (QCD) axion may modify the cooling rates of neutron stars
(NSs). The axions are produced within the NS cores from nucleon bremsstrahlung and …

I present an introduction and topical review on axions as a dark matter candidate. Emphasis
is placed on issues surrounding the cosmology of axion dark matter that are relevant for …

The last decade has seen unprecedented effort in dark matter model building at all mass
scales coupled with the design of numerous new detection strategies. Transformative …

We summarize the recent progress of the Axion Longitudinal Plasma Haloscope (ALPHA)
Consortium, a new experimental collaboration to build a plasma haloscope to search for …

The axion is a highly motivated elementary particle that could address two fundamental
questions in physics—the strong charge-parity (CP) problem and the dark matter mystery …

Several Pulsar Timing Array (PTA) collaborations have recently reported the evidence for a
stochastic gravitational-wave background (SGWB), which can unveil the formation of …

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 …
