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 …

Cosmological gravitational particle production (CGPP) is the creation of particles in an
expanding universe due solely to their gravitational interaction. These particles can play an …

Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant
instability, which can lead to a time evolution of the supermassive BH shadow. We study …

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 …

Black hole (BH) shadows can be used to probe new physics in the form of ultralight particles
via the phenomenon of superradiant instability. By directly affecting the BH mass and spin …

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 …

Massive vector fields feature in several areas of particle physics, eg, as carriers of weak
interactions, dark matter candidates, or an effective description of photons in a plasma. Here …

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 …

The recent observations by pulsar timing array (PTA) experiments suggest the existence of
stochastic gravitational wave background in the nano-Hz range. It can be a hint for the new …

A search for dark matter axions with masses> 10 μ eV/c 2 has been performed using the
HAYSTAC experiment's squeezed state receiver to achieve subquantum limited noise. This …
