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

Direct detection of dark matter—APPEC committee report
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 …

Dark matter from axion strings with adaptive mesh refinement
M Buschmann, JW Foster, A Hook, A Peterson… - Nature …, 2022 - nature.com
Axions are hypothetical particles that may explain the observed dark matter density and the

More axions from strings
M Gorghetto, E Hardy, G Villadoro - SciPost physics, 2021 - scipost.org
We study the contribution to the QCD axion dark matter abundance that is produced by
string defects during the so-called scaling regime. Clear evidence of scaling violations is …

Recent progress in the physics of axions and axion-like particles
The axion is a light pseudoscalar particle postulated to solve issues with the Standard
Model, including the strong CP problem and the origin of dark matter. In recent years, there …

Axion quasiparticles for axion dark matter detection
It has been suggested that certain antiferromagnetic topological insulators contain axion
quasiparticles (AQs), and that such materials could be used to detect axion dark matter …

Dark matter from an even lighter QCD axion: trapped misalignment
We show that dark matter can be accounted for by an axion that solves the strong CP
problem, but is much lighter than usual due to a Z Script N symmetry. The whole mass range …

Supernova axions convert to gamma rays in magnetic fields of progenitor stars
It has long been established that axions could have been produced within the nascent proto-
neutron star formed following the type II supernova SN1987A, escaped the star due to their …

ALP dark matter from kinetic fragmentation: opening up the parameter window
C Eröncel, R Sato, G Servant… - Journal of Cosmology …, 2022 - iopscience.iop.org
The main mechanism responsible for Axion-Like-Particle (ALP) production in the early
universe is the so-called misalignment mechanism. Three regimes have been investigated …

Axion minivoids and implications for direct detection
In the scenario in which QCD axion dark matter is produced after inflation, the Universe is
populated by large inhomogeneities on very small scales. Eventually, these fluctuations will …
