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 discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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 …

Axions and other very light axion-like particles appear in many extensions of the Standard
Model, and are leading candidates to compose part or all of the missing matter of the …

The existence of dark matter as evidenced by numerous indirect observations is one of the
most important indications that there must be physics beyond the Standard Model of particle …

Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition
whose observation would have fundamental implications for neutrino physics, theories …

We review several current aspects of dark matter theory and experiment. We overview the
present experimental status, which includes current bounds and recent claims and hints of a …

The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation
is determined, based on a full simulation, reconstruction, and event selection of the far …

The neutrino floor is a theoretical lower limit on WIMP-like dark matter models that are
discoverable in direct detection experiments. It is commonly interpreted as the point at which …
