[HTML][HTML] Feebly-interacting particles: FIPs 2022 workshop report

C Antel, M Battaglieri, J Beacham, C Boehm… - The European Physical …, 2023 - Springer
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 …

Dark photon limits: A handbook

A Caputo, AJ Millar, CAJ O'Hare, E Vitagliano - Physical Review D, 2021 - APS
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 …

New horizons: Scalar and vector ultralight dark matter

D Antypas, A Banerjee, C Bartram… - arxiv preprint arxiv …, 2022 - arxiv.org
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 …

Axion star explosions: A new source for axion indirect detection

M Escudero, CK Pooni, M Fairbairn, D Blas, X Du… - Physical Review D, 2024 - APS
If dark matter is composed of axions, then axion stars form in the cores of dark matter halos.
These stars are unstable above a critical mass, decaying to radio photons that heat the …

Dark photon oscillations in our inhomogeneous universe

A Caputo, H Liu, S Mishra-Sharma, JT Ruderman - Physical Review Letters, 2020 - APS
A dark photon kinetically mixing with the ordinary photon represents one of the simplest
viable extensions to the standard model, and would induce oscillations with observable …

Dark photon limits from patchy dark screening of the cosmic microwave background

F McCarthy, D Pîrvu, JC Hill, J Huang, MC Johnson… - Physical Review Letters, 2024 - APS
Dark photons that kinetically mix with the Standard Model photon give rise to new spectral
anisotropies (patchy dark screening) in the cosmic microwave background (CMB) due to …

Comparison of Low-Redshift Lyman- Forest Observations to Hydrodynamical Simulations with Dark Photon Dark Matter

JS Bolton, A Caputo, H Liu, M Viel - Physical review letters, 2022 - APS
Recent work has suggested that an additional≲ 6.9 eV per baryon of heating in the
intergalactic medium is needed to reconcile hydrodynamical simulations with Lyman-α forest …

Electromagnetic signatures of dark photon superradiance

A Caputo, SJ Witte, D Blas, P Pani - Physical Review D, 2021 - APS
Black hole superradiance is a powerful tool in the search for ultralight bosons. Constraints
on the existence of such particles have been derived from the observation of highly spinning …

Resonant conversion of wave dark matter in the ionosphere

C Beadle, A Caputo, SAR Ellis - Physical Review Letters, 2024 - APS
We consider resonant wavelike dark matter conversion into low-frequency radio waves in
the Earth's ionosphere. Resonant conversion occurs when the dark matter mass and the …

Photon-dark photon conversion with multiple level crossings

N Brahma, A Berlin, K Schutz - Physical Review D, 2023 - APS
Dark photons can oscillate into Standard Model (SM) photons via kinetic mixing. The
conversion probability depends sensitively on properties of the ambient background, such …
