Aspects of Axions and ALPs Phenomenology [PDF]
Journal of Physics: Conference Series, 2023 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.

Supernova Muons: New Constraints on Z′ Bosons, Axions and ALPs [PDF]
Journal of High Energy Physics, 2021 New light particles produced in supernovae can lead to additional energy loss and a consequent deficit in neutrino production in conflict with the neutrinos observed from Supernova 1987A (SN1987A). Contrary to the majority of previous SN1987A studies, we

The low-energy effective theory of axions and ALPs [PDF]
Journal of High Energy Physics, 2021 Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model, which interact with the known particles through higher-dimensional operators suppressed by the mass scale Λ of the new-physics ...

Journal of High Energy Physics, 2023 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.

Alternative dark matter candidates: axions and ALPs [PDF]
Proceedings of Neutrino Oscillation Workshop — PoS(NOW2018), 2019 The QCD axion and particles with similar properties (axion-like particles or ALPs) are excellent candidates to be the cold dark matter of the Universe. They are extremely different to the standard WIMP, however.

Searching for axions and ALPs from string theory [PDF]
Journal of Physics: Conference Series, 2014 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 ...

The Quest for an Intermediate-Scale Accidental Axion and Further ALPs [PDF]
Journal of High Energy Physics, 2014 The recent detection of the cosmic microwave background polarimeter experiment BICEP2 of tensor fluctuations in the B-mode power spectrum basically excludes all plausible axion models where its decay constant is above $10^{13}$ GeV.

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

Audible Axions with a Booster: Stochastic Gravitational Waves from Rotating ALPs [PDF]
, 2021 : Gravitational waves provide a novel way to probe axions or axion-like particles coupled to a dark photon field, even in the absence of couplings to Standard Model particles.

Constraints on Axions and Axionlike Particles from Fermi Large Area Telescope Observations of Neutron Stars [PDF]
, 2016 We present constraints on the nature of axions and axionlike particles (ALPs) by analyzing gamma--ray data from neutron stars using the Fermi Large Area Telescope.
