Extreme Axions Unveiled: a Novel Fluid Approach for Cosmological Modeling [PDF]

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.

Modulations in Spectra of Galactic Gamma-ray sources as a result of photon-ALPs mixing

, 2017
International audienceAxion like particles (ALPs) are fundamental pseudo scalar particles with properties similar to Axions which are a well-known extensions of the standard model to solve the strong CP problem in Quantum Chromodynamics.

Axion detection via superfluid 3He ferromagnetic phase and quantum measurement techniques

Journal of High Energy Physics
We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid 3He for the axion dark matter detection. This approach is striking in that it is sensitive to the axion-nucleon coupling, one of the most important features of ...

Sensitivity to kaon decays to ALPs at fixed target experiments [PDF]

We study the sensitivity of fixed target experiments to hadronically coupled axionlike particles (ALPs) produced in kaon decays, with a particular emphasis on current and upcoming Short-Baseline Neutrino (SBN) experiments.

Froggatt-Nielsen ALP

Journal of High Energy Physics
The Froggatt-Nielsen (FN) mechanism, a prominent framework for explaining the observed flavor hierarchies, generically predicts the existence of an axion-like particle (ALP). This work examines a class of FN models based on ℤ N discrete symmetries.

Fuzzy dark matter from string axions [PDF]

In this thesis we study the viability for ultra-light axions coming from moduli stabilisation in the Large volume scenario to fit recent observations about the dark matter presence in several galaxies and clusters.

QCD axion bubbles in the presence of ALP resonant conversion

Communications in Theoretical Physics
Abstract The QCD axion bubbles can form due to an explicit breaking of the Peccei–Quinn symmetry in the early Universe. In this paper, we investigate the modified formation of a QCD axion bubble in the presence of an axionlike particle (ALP), considering its resonant conversion to a QCD axion. We consider a general scenario where the QCD
