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

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 $g_{\alpha \gamma \gamma} > 2 \times 10^{-11}\ \rm{GeV^{-1}}$, improving the sensitivity by a factor of $10^3$ compared to ...

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.

Solar axions in large extra dimensions [PDF]
, 2021 International audienceThe axion could be used as a probe for extra dimensions. In large extra dimensions, besides the QCD axion one obtains an infinite tower of massive Kaluza-Klein (KK) states.

The quest for an intermediate-scale accidental axion and further ALPs [PDF]
Journal of High Energy Physics, 2014 La détection récente de l'expérience du polarimètre de fond cosmologique à micro-ondes BICEP2 des fluctuations des tenseurs dans le spectre de puissance en mode B exclut fondamentalement tous les modèles d'axions plausibles où sa constante de désintégration est supérieure à $ 10^{13}$ GeV.

Neutrino oscillation in ALPs matter
, 2022 Axions and axion-like particles (ALPs) are some of the most popular candidates for dark matter [1]. Axions are also considered [2] as new physics contributions to the muon g – 2 .

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 ...
