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 …

Abstract The Einstein Telescope (ET), the European project for a third-generation
gravitational-wave detector, has a reference configuration based on a triangular shape …

This Horizon Study describes a next-generation ground-based gravitational-wave
observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic …

Now that detection of gravitational-wave signals from the coalescence of extra-galactic
compact binary star mergers has become nearly routine, it is intriguing to consider other …

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 …

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark
discovery, potentially providing a significant clue to some of our most basic, big-picture …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

We present a search for dark photon dark matter that could couple to gravitational-wave
interferometers using data from Advanced LIGO and Virgo's third observing run. To perform …

Numerous theories extending beyond the standard model of particle physics predict the
existence of bosons that could constitute dark matter. In the standard halo model of galactic …
