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 …

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 …

In the late 1970s, the axion was proposed as a solution to the strong CP problem, ie, the
puzzle why the strong interactions conserve parity P and the product CP of charge …

We introduce the Broadband Reflector Experiment for Axion Detection (BREAD) conceptual
design and science program. This haloscope plans to search for bosonic dark matter across …

We study the contribution to the QCD axion dark matter abundance that is produced by
string defects during the so-called scaling regime. Clear evidence of scaling violations is …

Uncovering the nature of dark matter is one of the most important goals of particle physics.
Light bosonic particles, such as the dark photon, are well-motivated candidates: they are …

Axions are some of the best motivated particles beyond the Standard Model. We show how
the attractive self-interactions of dark matter (DM) axions over a broad range of masses, from …
