Direct search for dark matter axions excluding ALP cogenesis in the 63- to 67-μeV range with the ORGAN experiment. [PDF]
Sci Adv, 2022 The standard model axion seesaw Higgs portal inflation (SMASH) model is a well-motivated, self-contained description of particle physics that predicts axion dark matter particles to exist within the mass range of 50 to 200 micro–electron volts.

Predictions for axion couplings from ALP cogenesis [PDF]
Journal of High Energy Physics, 2021 Abstract Adding an axion-like particle (ALP) to the Standard Model, with a field velocity in the early universe, simultaneously explains the observed baryon and dark matter densities. This requires one or more couplings between the ALP and photons, nucleons, and/or electrons that are predicted as functions of the ALP mass.

Getting the most on supernova axions [PDF]
Physical Review D, 2023 Axion-like particles (ALPs) coupled to nucleons might be copiously emitted from a supernova (SN) core. We extend existing bounds on free-streaming ALPs to the case in which these are so strongly-interacting with the nuclear matter to be trapped in the SN

Constraining postinflationary axions with pulsar timing arrays [PDF]
Physical Review D, 2023 Models that produce Axion-Like-Particles (ALP) after cosmological inflation due to spontaneous $U(1)$ symmetry breaking also produce cosmic string networks.

, 2007 Recently, the PVLAS collaboration has reported evidence for an anomalous rotation of the polarization of light in vacuum in the presence of a transverse magnetic field. This may be explained through the production of a new light spin-zero (axion-like) neutral particle coupled to two photons.

Extreme axions unveiled: A novel fluid approach for cosmological modeling [PDF]
Physical Review D, 2023 Axion-like particles (ALPs) are a well-motivated dark matter candidate that solve some of the problems in the clustering of large scale structure in cosmology.

Higher-Order Corrections to the Effective Field Theory of Low-Energy Axions [PDF]
Symmetry, 2023 Dark matter (DM) can be composed of a collection of axions, or axion-like particles (ALPs), whose existence is due to the spontaneous breaking of the Peccei–Quinn U(1) symmetry, which is the most compelling solution of the strong CP-problem of quantum ...

New bounds on axion-like particles from MicroBooNE
Journal of High Energy Physics, 2022 Neutrino experiments lie at the edge of the intensity frontier and therefore can be exploited to search for new light particles weakly coupled to the visible sector.

A First Application of Machine and Deep Learning for Background Rejection in the ALPS II TES Detector [PDF]
Annals of Physics, 2023 Axions and axion‐like particles are hypothetical particles predicted in extensions of the standard model and are promising cold dark matter candidates. The Any Light Particle Search (ALPS II) experiment is a light‐shining‐through‐the‐wall experiment that
