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 …

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 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 …

Solid-state detectors with a low energy threshold have several applications, including
searches of non-relativistic halo dark-matter particles with sub-GeV masses. When …

We report the first result of a direct search for a cosmic axion background (C a B)—a
relativistic background of axions that is not dark matter—performed with the axion …

We propose the use of the Earth as a transducer for ultralight dark-matter detection. In
particular, we point out a novel signal of kinetically mixed dark-photon dark matter: a …

A bstract In the presence of axion dark matter, fermion spins experience an “axion wind”
torque and an “axioelectric” force. We investigate new experimental probes of these effects …

Existing searches for cosmic axions relics have relied heavily on the axion being
nonrelativistic and making up dark matter. However, light axions can be copiously produced …

A bstract We revisit the calculation of bosonic dark matter absorption via electronic
excitations. Working in an effective field theory framework and consistently taking into …
