Aspects of Axions and ALPs Phenomenology [PDF]
Journal of Physics: Conference Series, 2022 The physics of axions and axion-like particles (ALPs) is enjoying an incredibly productive period, with many new experimental proposals, theoretical idea, and original astrophysical and cosmological arguments which help the search effort.

Journal of High Energy Physics, 2019 Conventional approaches to probing axions and axion-like particles (ALPs) typically rely on a coupling to photons. However, if this coupling is extremely weak, ALPs become invisible and are effectively decoupled from the Standard Model. Here we show that

Searching for axions and ALPs from string theory
Journal of Physics: Conference Series, 2012 We review searches for closed string axions and axion–like particles (ALPs) in IIB string flux compactifications. For natural values of the background fluxes and TeV scale gravitino mass, the moduli stabilisation mechanism of the LARGE Volume Scenario ...

Axions and ALPs: a very short introduction
, 2017 The QCD axion was originally predicted as a dynamical solution to the strong CP problem. Axion like particles (ALPs) are also a generic prediction of many high energy physics models including string theory.

Axion and ALP search with the Any Light Particle Search II experiment at DESY
Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2023), 2023 The Any Light Particle Search II (ALPS II) is a Light-Shining-Through-a-Wall experiment at DESY in Hamburg, Germany, which hunts for axions and axion-like particles in the sub-meV mass range with an axion-photon-photon coupling $g_{\alpha \gamma \gamma} >

DarkGEO: a large-scale laser-interferometric axion detector [PDF]
New Journal of PhysicsAxions and axion-like particles (ALPs) are leading candidates for dark matter. They are well motivated in many extensions of the standard model and supported by astronomical observations.

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.

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.

Journal of High Energy Physics, 2023 Abstract The Effective Field Theory (EFT) Lagrangian for a generic axion-like particle (ALP) has many free parameters, and leaves quite some freedom for the expected phenomenology. In this work, we set up more constrained EFTs by enforcing true axion-like properties for the ALP.

ALPs and Heavy Hadron Chiral Perturbation Theory [PDF]
, 2022 Axion Like Particles (ALPs) belong to a well motivated class of particles which are part of a more complete UV theory. In this work, we initiate and present the inclusion of such ALPs or the conventional axions in the Heavy Hadron Chiral Perturbation ...
